This backwardness probably arose from the indisposition of the people to abandon the nomad life in which they had been born and bred, and to settle in fixed abodes, and perhaps also from a dislike of the exterminating warfare incidental to a complete dispossessing of the Canaanites.

How long are ye slack to go to possess the land - We find an unaccountable backwardness in this people to enter on the inheritance which God had given them! They had so long been supported by miracle, without any exertions of their own, that they found it difficult to shake themselves from their inactivity. When it was necessary that all the people should go out to battle, they went with a measure of confidence, expecting miraculous help from God, and confiding in their numbers, but when each tribe found it necessary to fight for itself, in order to its establishment and the extension of its borders, it was discouraged, and chose rather a life of inglorious ease than the possession of an inheritance which would cost it much labor to conquer.

And Joshua said unto the children of Israel,.... To those of the seven tribes:

how long are you slack to go to possess the land which the Lord God of your fathers hath given you? not that they might have taken possession of it of themselves, without having it assigned to them by lot; that they did not do this, is not what is complained of, and they stand reproved for; but that when two tribes and a half had received their inheritance, these seemed indifferent to it, showed no inclination and disposition towards it, and much less eagerness to have a settlement, and did not apply to the court for it; which dilatoriness might arise from the present affluence of all good things they enjoyed through the spoils of the enemy; and partly through slothfulness, being tired of the war, and perceiving that they must be involved in it again to dispossess the Canaanites of some of the cities that would fall to their lot; and, perhaps, their slackness might be the more increased, by observing the dissatisfaction of the tribes with the lot they had received, and therefore waited till things were adjusted to greater satisfaction.

But, for the reasons explained in Joshua 14:1, these tribes showed themselves "slack to go to possess the land which the Lord had given them," i.e., not merely to conquer it, but to have it divided by lot, and to enter in and take possession. Joshua charged them with this, and directed them to appoint three men for each of the seven tribes, that they might be sent out to go through the land, and describe it according to the measure of their inheritance. "According to their inheritance," i.e., with special reference to the fact that seven tribes were to receive it for their inheritance. The description was not a formal measurement, although the art of surveying was well known in Egypt in ancient times, and was regularly carried out after the annual inundations of the Nile (Herod. ii. 109; Strabo, xvii. 787; Diod. Sic. i. 69); so that the Israelites might have learned it there. But כּתב does not mean to measure; and it was not a formal measurement that was required, for the purpose of dividing the land that yet remained into seven districts, since the tribes differed in numerical strength, and therefore the boundaries of the territory assigned them could not be settled till after the lots had been cast. The meaning of the word is to describe; and according to Joshua 18:9, it was chiefly to the towns that reference was made: so that the description required by Joshua in all probability consisted simply in the preparation of lists of the towns in the different parts of the land, with an account of their size and character; also with "notices of the quality and condition of the soil; what lands were fertile, and what they produced; where the country was mountainous, and where it was level; which lands were well watered, and which were dry; and any other things that would indicate the character of the soil, and facilitate a comparison between the different parts of the land" (Rosenmller). The reasons which induced Joshua to take steps for the first time now for securing a survey of the land, are given in Joshua 14:1. The men chosen for the purpose were able to carry out their task without receiving any hindrance from the Canaanites. For whilst the latter were crushed, if not exterminated, by the victories which the Israelites had gained, it was not necessary for the twenty-one Israelitish men to penetrate into every corner of the land, and every town that was still inhabited by the Canaanites, in order to accomplish their end.

And Joshua said unto the children of Israel, How long are ye slack to go to possess the land, which the LORD God of your fathers hath given you?

18:3 How long are you slack - This slackness is supposed to arise from an opinion of the impossibility of making any regular distribution of the parts, 'till the whole were more exactly surveyed, which accordingly is here done. Likewise, being weary of war, and having sufficient plenty of all things, they were unwilling to run into new hazards.

3. How long are ye slack to go to possess the land, which the Lord God of your fathers hath given you-This reproof conveys an impression that the seven tribes were dilatory to a criminal extent.

18:2-10 After a year or more, Joshua blamed their slackness, and told them how to proceed. God, by his grace, has given us a title to a good land, the heavenly Canaan, but we are slack to take possession of it; we enter not into that rest, as we might by faith, and hope, and holy joy. How long shall it be thus with us? How long shall we thus stand in our own light, and forsake our own mercies for lying vanities? Joshua stirs the Israelites up to take possession of their lots. He is ready to do his part, if they will do theirs.
