The final phrase of Leviticus 18:1–30 reminds the Israelites of the basis of these laws. The Lord himself is the one to define sexual conduct and sexual purity in the lives of his people. The phrase, I am the Lord,
forms an inclusion here and at the beginning of the chapter.
30 Vous observerez mes commandements, et vous ne pratiquerez aucun des usages abominables qui se pratiquaient avant vous, vous ne vous en souillerez pas. Je suis l'Eternel, votre Dieu.
