Leviticus 27:29

“None devoted, which shall be devoted of men, shall be redeemed, etc.] This is said, not of such men as are devoted to the Lord, as in the preceding verse; for it is not said here as there, “none devoted unto the Lord”, but of such as are devoted to ruin and destruction, for whom there was no redemption, but they must die; nor is it said, “which is devoted by men, but of men”, or from among men; whether they be devoted by God himself, as all idolaters, and particularly the seven nations of the land of Canaan, and especially the Amalekites, who therefore were not to be spared on any account, but to be put to death, (<022220>Exodus 22:20 <050701> Deuteronomy 7:1,2 20:16,17 25:19 <091503>1…”

“shall surely be put to death--This announcement imported not that the person was to be sacrificed or doomed to a violent death; but only that he should remain till death unalterably in the devoted condition. The preceding regulations were evidently designed to prevent rashness in vowing (Ecc 5:4) and to encourage serious and considerate reflection in all matters between God and the soul (Luk 21:4).”

“Devoted of men - Not by men, as some would elude It; but of men, for it is manifest both from this and the foregoing verses, that men are here not the persons devoting, but devoted to destruction, either by God's sentence, as idolaters, Exo 22:20; Deu 23:15, the Canaanites, Deu 20:17, the Amalekites, Deu 25:19, and Sa1 15:3, Sa1 15:26, Benhaded, Kg1 20:42, or by men, in pursuance of such a sentence of God, as Num 21:2-3, Num 31:17, or for any crime of an high nature, as Jdg 21:5; Jos 17:15. But this is not to be generally understood, as some have taken it, as if a Jew might by virtue of this Text, devote his child or his servant to the Lord, and thereby oblige himself to put them to death.…”

“27:29 set apart for destruction (Hebrew kherem): The context here is the war for the conquest of Canaan, when cities, animals, and people deemed holy to some other god were set apart to be destroyed.”

“None: Num 21:2, Num 21:3; Sa1 15:18-23 which shall be devoted: That is, either that every person devoted to the service of God shall not be redeemed, but die in that devoted state, or, that such as were devoted to death by appointment and law of God, as the Canaanites were, shall be put to death.
