(5) Ye shall therefore keep my statutes. Better, and ye shall keep my ordinances. The word here rendered by "statutes" is the same which the Authorised Version translates ordinances in Leviticus 18:3-4.

He shall live in them.--Better, he shall live by or through them; that is, by observing them the law abiding will live a happy and prosperous life, since disobedience will expose the offender to the penalty of death. The spiritual authorities in the time of the second Temple interpreted this clause to mean that he who obeys these laws shall have eternal life. Hence the ancient Chaldee Versions translate it, "Shall have life eternal." This passage is quoted both in the Prophets (Ezekiel 20:11; Ezekiel 20:13; Ezekiel 20:21; Nehemiah 9:29) and by St. Paul (Romans 10:5; Galatians 3:12), who contrasts this promise made to works with the promise of the Gospel made to faith.

18:1-30 Unlawful marriages and fleshly lusts. - Here is a law against all conformity to the corrupt usages of the heathen. Also laws against incest, against brutal lusts, and barbarous idolatries; and the enforcement of these laws from the ruin of the Canaanites. God here gives moral precepts. Close and constant adherence to God's ordinances is the most effectual preservative from gross sin. The grace of God only will secure us; that grace is to be expected only in the use of the means of grace. Nor does He ever leave any to their hearts' lusts, till they have left him and his services.Ye shall therefore keep my statutes, and my judgments,.... The same as before; these they were to keep in their minds and memories, and to observe them and do them:

which if a man do he shall live in them; live a long life in the land of Canaan, in great happiness and prosperity, see Deuteronomy 30:20; for as for eternal life, that was never intended to be had, nor was it possible it could be had and enjoyed by obedience to the law, which fallen man is unable to keep; but is what was graciously promised and provided the covenant of grace, before the world was, to come through Christ, as a free gift to all that believe in him, see Galatians 3:11; though some Jewish writers interpret this of eternal life, as Jarchi, Aben Ezra, and Ben Gersom:

I am the Lord; that has enjoined these statutes and judgments, and promised life to the doers of them, able and faithful to perform what is promised.
