Joshua warned God's people not to marry their neighbors who worshiped many gods. Such close relationships could lead the Israelites to be unfaithful to God (Deuteronomy 7:3–4). However, people from Canaan who wanted to worship the Lord and join God's people were welcome (Joshua 6:25; Ruth 4:10). Race, language, and ethnic group did not affect God's rule against marrying non-Israelites. It was a matter of remaining loyal to the Lord (see 2 Corinthians 6:14–15).
