These are the statutes and judgments and laws, which the LORD made between him and the children of Israel in mount {y} Sinai by the hand of Moses.

(y) Fifty days after they came out of Egypt.

Wesley's Notes

26:46 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.

Jamieson-Fausset-Brown Bible Commentary

46. 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].

Matthew Henry's Concise Commentary

26:40-46 Among the Israelites, persons were not always prosperous or afflicted according to their obedience or disobedience. But national prosperity was the effect of national obedience, and national judgments were brought on by national wickedness. Israel was under a peculiar covenant. National wickedness will end in the ruin of any people, especially where the word of God and the light of the gospel are enjoyed. Sooner or later, sin will be the ruin, as well as the reproach, of every people. Oh that, being humbled for our sins, we might avert the rising storm before it bursts upon us! God grant that we may, in this our day, consider the things which belong to our eternal peace.
