Leviticus 26:46

“These [are] the statutes, and judgments, and laws, etc.] Which refer not only to those in this chapter, but in all the preceding chapters in this book, and respect them all, whether ceremonial, moral, or judicial, which may be signified by these three words: which the Lord made between him and the children of Israel; the Targums of Onkelos and Jonathan are, “between his Word and the children of Israel:” in Mount Sinai; or near it, in the wilderness of it, while the children of Israel lay encamped about it: by the hand of Moses; they were first delivered to him, and by means of him to the people.”

“These are the statutes and judgments and laws--It has been thought by some that the last chapter was originally placed after the twenty-fifth [ADAM CLARKE], while others consider that the next chapter was added as an appendix, in consequence of many people being influenced by the promises and threats of the preceding one, to resolve that they would dedicate themselves and their possessions to the service of God [CALMET]. Next: Leviticus Chapter 27”

“These are the laws which the Lord made between him and the children of Israel - Hereby his communion with his church is kept up. He manifests not only his dominion over them, but his favour to them, by giving them his law. And they manifest not only their holy fear, but their holy love by the observance of it. And thus it is made between them rather as a covenant than as a law: for he draws them with the cords of a man. Next: Leviticus Chapter 27”

“As this verse appears to be the proper concluding verse of the whole book, Dr. A. Clarke thinks that the Lev 27:1 originally followed Lev 25:1. Others suppose that the 27th chapter was added after the book was finished; and, therefore, there is apparently a double conclusion, one at the end of this, and another at the end of the 27th chapter. All the ancient versions agree in concluding both chapters in nearly the same way. the statutes: Lev 27:34; Deu 6:1, Deu 12:1, Deu 13:4; Joh 1:17 in mount Sinai: Lev 25:1 by the hand: Lev 8:36; Num 4:37; Psa 77:20 Next: Leviticus Chapter 27”

“Lev 26:46 contains the close of the entire book, or rather of the whole of the covenant legislation from Ex 25 onwards, although the expression "in Mount Sinai" points back primarily to Lev 25:1. Next: Leviticus Chapter 27”
