The officers dedicated it - See Exodus 5:6 note.

Compare the marginal references. The expression is appropriate, because various ceremonies of a religious kind were customary among the Jews on taking possession of a new house. The immunity conferred in this verse lasted, like that in Deuteronomy 20:7 (compare Deuteronomy 24:5), for one year.

That hath built a new house, and hath not dedicated it? - From the title of Psalm 30:1-12, - A Psalm or Song at the Dedication of the House of David - it is evident that it was a custom in Israel to dedicate a new house to God with prayer, praise, and thanksgiving; and this was done in order to secure the Divine presence and blessing, for no pious or sensible man could imagine he could dwell safely in a house that was not under the immediate protection of God. Hence it has been a custom in the most barbarous nations to consecrate a part of a new house to the deity they worshipped. The houses of the inhabitants of Bonny, in Africa, are generally divided into three apartments: one is a kind of state room or parlour; another serves for a common room, or kitchen; and the third is dedicated to the Juju, the serpent god, which they worship; for even those savages believe that in every house their god should have his temple! At the times of dedication among the Jews, besides prayer and praise, a feast was made, to which the relatives and neighbors were invited. Something of this custom is observed in some parts of our own country in what is called warming the house; but in these cases the feasting only is kept up - the prayer and praise forgotten! so that the dedication appears to be rather more to Bacchus than to Jehovah, the author of every good and perfect gift.

And the officers shall speak unto the people,.... What these officers were is not easy to say; they seem not to be officers of the army, for they are distinguished from captains of the armies, Deuteronomy 20:9, unless they can be thought to be general officers; but the word for them is the same that is used of such that attended the judges and were ministers to them, Deuteronomy 16:18, and perhaps they were a sort of heralds that published and proclaimed what the anointed of war had said; and so the above writer (h) affirms, that what here follows was first spoken by him, and after that (what is said, Deuteronomy 20:3) the anointed of war speaks, saying:

what man is there,.... (to the end of Deuteronomy 20:7) thus far the anointed of war speaks, and then an officer causes all the people to hear it with an high voice, saying:

what man is there that hath built a new house, and hath not dedicated it? or perfected it, as the Targum of Jonathan, not quite finished it, has not, as that paraphrast says, fixed in it the door posts, or rather perhaps he means the Mezuzah, or writing, which the Jews thought themselves obliged to fasten to the door posts of their houses; see Deuteronomy 11:20 until this was done, an house was not thought to be completed; though Jarchi interprets this of inhabitation; of a man's having built a house, but has not yet dwelt in it; see Deuteronomy 28:30, so Josephus (i) explains it, of its not having been used and enjoyed by a man a full year; but there seems to be something more than all this in dedication; for though it does not signify a consecration or dedication of it to holy uses, as the dedication of the tabernacle and temple, yet there was something done, some ceremony used at entrance into a new house; a good man entered into it, no doubt, with prayer and praise, as the thirtieth psalm was composed by David at the dedication of his house; see Nehemiah 12:27 and perhaps it was usual to have their friends together, and make a cheerful entertainment on the occasion. Ben Melech on the place, assures us it was a custom to make a feast and merriment at eating the first meal in a new house:

let him go and return to his house, lest he die in the battle, and another man dedicate it; or perfect it, as the above Targum, or dwell in it, as well as have the pleasure of entertaining his friends in it at the first opening of it; this was either a command, enjoining a man, in such a circumstance, to return, and so the rest that follow, or a permission to him, allowing him to do it if he thought fit.

Moreover, the shoterim, whose duty it was, as the keepers of the genealogical tables, to appoint the men who were bound to serve, were to release such of the men who had been summoned to the war as had entered into domestic relations, which would make it a harder thing for them to be exposed to death than for any of the others: for example, any man who had built a new house and had not yet consecrated it, or had planted a vineyard and not yet eaten any of the fruit of it, or was betrothed to a wife and had not yet married her, - that such persons might not die before they had enjoyed the fruits of what they had done. "Who is the man, who," i.e., whoever, every man who. "Consecrated the house," viz., by taking possession and dwelling in it; entrance into the house was probably connected with a hospitable entertainment. According to Josephus (Ant. iv. 8, 41), the enjoyment of them was to last a year (according to the analogy of Deuteronomy 24:5). The Rabbins elaborated special ceremonies, among which Jonathan in his Targum describes the fastening of slips with sentences out of the law written upon them to the door-posts, as being the most important (see at Deuteronomy 6:9 : for further details, see Selden, de Synedriis l. iii. c. 14, 15). Cerem is hardly to be restricted to vineyards, but applied to olive-plantations as well (see at Leviticus 19:10). חלּל, to make common, is to be explained from the fact, that when fruit-trees were planted (Leviticus 19:23.), or vines set (Judges 19:24), the fruit was not to be eaten for the first three years, and that of the fourth year was to be consecrated to the Lord; and it was only the fruit that was gathered in the fifth year which could be applied by the owner to his own use, - in other words, could be made common. The command to send away from the army to his own home a man who was betrothed but had not yet taken his wife, is extended still further in Deuteronomy 24:5, where it is stated that a newly married man was to be exempt for a whole year from military service and other public burdens. The intention of these instructions was neither to send away all persons who were unwilling to go into the war, and thus avoid the danger of their interfering with the readiness and courage of the rest of the army in prospect of the battle, nor to spare the lives of those persons to whom life was especially dear; but rather to avoid depriving any member of the covenant nation of his enjoyment of the good things of this life bestowed upon him by the Lord.

And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not {c} dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it.

(c) For when they first entered to dwell in a house, they gave thanks to God, acknowledging that they had that benefit by his grace.

20:5 What man - This and the following exceptions are to be understood only of a war allowed by God, not in a war commanded by God, not in the approaching war with the Canaanites, from which even the bridegroom was not exempted, as the Jewish writers note.

5-8. And the officers shall speak unto the people-literally, Shoterim, who are called "scribes" or "overseers" (Ex 5:6). They might be keepers of the muster-roll, or perhaps rather military heralds, whose duty it was to announce the orders of the generals (2Ch 26:11). This proclamation (De 20:5-8) must have been made previous to the priest's address, as great disorder and inconvenience must have been occasioned if the serried ranks were broken by the departure of those to whom the privilege was granted. Four grounds of exemption are expressly mentioned: (1) The dedication of a new house, which, as in all Oriental countries still, was an important event, and celebrated by festive and religious ceremonies (Ne 12:27); exemption for a year. (2) The planting of a vineyard. The fruit of the first three years being declared unfit for use, and the first-fruits producible on the fourth, the exemption in this case lasted at least four years. (3) The betrothal of a wife, which was always a considerable time before marriage. It was deemed a great hardship to leave a house unfinished, a new property half cultivated, and a recently contracted marriage; and the exemptions allowed in these cases were founded on the principle that a man's heart being deeply engrossed by something at a distance, he would not be very enthusiastic in the public service. (4) The ground of exemption was cowardice. From the composition of the Israelitish army, which was an irregular militia, all above twenty years being liable to serve, many totally unfit for war must have been called to the field; and it was therefore a prudential arrangement to rid the army of such unwarlike elements-persons who could render no efficient service, and the contagion of whose craven spirit might lead to panic and defeat.

20:1-9 In the wars wherein Israel engaged according to the will of God, they might expect the Divine assistance. The Lord was to be their only confidence. In these respects they were types of the Christian's warfare. Those unwilling to fight, must be sent away. The unwillingness might arise from a man's outward condition. God would not be served by men forced against their will. Thy people shall be willing, Ps 110:3. In running the Christian race, and fighting the good fight of faith, we must lay aside all that would make us unwilling. If a man's unwillingness rose from weakness and fear, he had leave to return from the war. The reason here given is, lest his brethren's heart fail as well as his heart. We must take heed that we fear not with the fear of them that are afraid, Isa 8:12.
