Judges 3:4-6

4They were left to test the Israelites to see whether they would obey the LORD ’s commands, which he had given their ancestors through Moses. 5The Israelites lived among the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites.

6They took their daughters in marriage and gave their own daughters to their sons, and served their gods.
