The Lord began a list of sexual sins, saying,
“The man who commits adultery with another man’s wife, he who commits adultery with his neighbor’s wife, the adulterer and the adulteress, shall surely be put to death” (Leviticus 20:10).
Then He listed others:
1. Incest (Leviticus 20:11, 12)
2. Homosexuality (Leviticus 20:13)
3. Marriage to a daughter and mother (Leviticus 20:14)
4. Bestiality (Leviticus 20:15, 16)
These were things that the Canaanites had committed and for which the Lord was casting them out, and He did not want His people doing the same things, or He would likewise remove them.
We can keep our land pure by not engaging in these sins also, lest the Lord visit a nation with punishment like He did the Israelites and the Canaanites.
