Charles Ellicott Commentary Leviticus 18:24

"Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out from before you;" — Leviticus 18:24 (ASV)

Defile not ye yourselves. —The Lawgiver who solemnly introduced these precepts by five verses of preamble at the beginning of the chapter (Leviticus 18:1–5), now concludes by an equally solemn appeal to God’s people sacredly to observe them in all their integrity, since the violation of them (Leviticus 18:6–23) has branded those nations with infamy, and brought about their national destruction, and expulsion from the very land which is now to be given to the Israelites.
