That was by the sanctuary of the Lord - i. e. the spot where Abraham and Jacob had sacrificed and worshipped, and which might well be regarded by their posterity as a holy place or sanctuary. Perhaps the very altar of Abraham and Jacob was still remaining.

And Joshua wrote these words,.... Which had passed between him and the people:

in the book of the law of God; written by Moses, and which he ordered to be put in the side of the ark, and that being now present, the book could be easily taken out, and these words inserted in it, Deuteronomy 31:26,

and took a great stone: on which also might be inscribed the same words:

and set it up there under an oak, that was by the sanctuary of the Lord; or "in it" (a); that is, in the field or place where the ark was, which made it sacred, and upon which account the place was called a sanctuary, or an holy place; for there is no need to say that the tabernacle or sanctuary itself was brought hither, only the ark; and much less can it be thought that an oak should be in it; though it was not improbable, that had it been thither brought, it might have been placed under, or by an oak, as we render it; and it is a tradition of the Jews, which both Jarchi and Kimchi make mention of, that this was the same oak under which Jacob hid the strange gods of his family in Shechem, Genesis 35:4; Mr. Mede (b) is of opinion that neither ark nor tabernacle were here, but that by "sanctuary" is meant a "proseucha", or place for prayer; such an one as in later times was near Shechem, as Epiphanius (c) relates, built by the Samaritans in imitation of the Jews; but it is a question whether there were any such places so early as the times of Joshua, nor is it clear that such are ever called sanctuaries.

(a) "in sanctuario", V. L. Pagninus, Montanus, Tigurine version, Vatasblus, Junius & Tremellius. (b) Discourse 18. p. 66. (c) Contr. Haeres. l. 3. tom. 2. Haeres. 80.

All these things (האלּה הדּברים are not merely the words spoken on both sides, but the whole ceremony of renewing the covenant) Joshua wrote in the law-book of God, i.e., he wrote them in a document which he placed in the law-book of Moses, and then set up a large stone, as a permanent memorial of what had taken place, on the spot where the meeting had been held, "under the oak that was in the sanctuary of Jehovah." As בּמקדּשׁ neither means "at the sanctuary," nor near the sanctuary, nor "in the place where the sanctuary was set up;' the "sanctuary of Jehovah" cannot signify "the ark of the covenant, which had been brought from the tabernacle to Shechem, for the ceremony of renewing the covenant." Still less can we understand it as signifying the tabernacle itself, since this was not removed from place to place for particular sacred ceremonies; nor can it mean an altar, in which an oak could not possibly be said to stand; nor some other illegal sanctuary of Jehovah, since there were none in Israel at that time. The sanctuary of Jehovah under the oak at Shechem was nothing else than the holy place under the oak, where Abraham had formerly built an altar and worshipped the Lord, and where Jacob had purified his house from the strange gods, which he buried under this oak, or rather terebinth tree (Genesis 12:6-7; Genesis 35:2, Genesis 35:4). This is the explanation adopted by Masius, J. D. Michaelis, and Hengstenberg (Diss. ii. p. 12). In Joshua 24:27 Joshua explains to the people the meaning of the stone which he had set up. The stone would be a witness against the people if they should deny their God. As a memorial of what had taken place, the stone had heard all the words which the Lord had addressed to Israel, and could bear witness against the people, that they might not deny their God. "Deny your God," viz., in feeling, word, or deed.

And Joshua wrote these words in the book of the law of God, and took a great stone, and set it up there under an oak, that was by the sanctuary of the LORD.

24:26 These words - That is, this covenant or agreement of the people with the Lord. In the book - That is, in the volume which was kept in the ark, Deut 31:9,26, whence it was taken and put into this book of Joshua: this he did for the perpetual remembrance of this great and solemn action, to lay the greater obligation upon the people to be true to their engagement; and as a witness for God, against the people, if afterward he punished them for their defection from God, to whom they had so solemnly and freely obliged themselves. Set it up - As a witness and monument of this great transaction, according to the custom of those ancient times. Possibly this agreement was written upon this stone, as was then usual. By the sanctuary - That is, near the place where the ark and tabernacle then were; for tho' they were forbidden to plant a grove of trees near unto the altar, as the Gentiles did, yet they might for a time set up an altar, or the ark, near a great tree which had been planted there before.

26. Joshua wrote these words in the book of the law of God-registered the engagements of that solemn covenant in the book of sacred history.

took a great stone-according to the usage of ancient times to erect stone pillars as monuments of public transactions.

set it up there under an oak-or terebinth, in all likelihood, the same as that at the root of which Jacob buried the idols and charms found in his family.

that was by the sanctuary of the Lord-either the spot where the ark had stood, or else the place around, so called from that religious meeting, as Jacob named Beth-el the house of God.

24:15-28 It is essential that the service of God's people be performed with a willing mind. For LOVE is the only genuine principle whence all acceptable service of God can spring. The Father seeks only such to worship him, as worship him in spirit and in truth. The carnal mind of man is enmity against God, therefore, is not capable of such spiritual worship. Hence the necessity of being born again. But numbers rest in mere forms, as tasks imposed upon them. Joshua puts them to their choice; but not as if it were indifferent whether they served God or not. Choose you whom ye will serve, now the matter is laid plainly before you. He resolves to do this, whatever others did. Those that are bound for heaven, must be willing to swim against the stream. They must not do as the most do, but as the best do. And no one can behave himself as he ought in any station, who does not deeply consider his religious duties in family relations. The Israelites agree with Joshua, being influenced by the example of a man who had been so great a blessing to them; We also will serve the Lord. See how much good great men do, by their influence, if zealous in religion. Joshua brings them to express full purpose of heart to cleave to the Lord. They must come off from all confidence in their own sufficiency, else their purposes would be in vain. The service of God being made their deliberate choice, Joshua binds them to it by a solemn covenant. He set up a monument of it. In this affecting manner Joshua took his last leave of them; if they perished, their blood would be upon their own heads. Though the house of God, the Lord's table, and even the walls and trees before which we have uttered our solemn purposes of serving him, would bear witness against us if we deny him, yet we may trust in him, that he will put his fear into our hearts, that we shall not depart from him. God alone can give grace, yet he blesses our endeavours to engage men to his service.
