Genesis 34:8

Hamor suggested a marriage alliance for mutual economic gain. But God had already promised Jacob everything, including the land (34:10; see 14:21–24). Hamor wanted to control Israel’s wealth (34:23). Trusting the Canaanites would not lead to anything good.

For some of these reasons, the law of Moses did not allow Israelites to marry Canaanites (see Exodus 23:27–33; Deuteronomy 7:1–5). The exception would be if they converted (see Joshua 2:1–15; 6:23–25; Matthew 1:5).

After Jacob and his family settled in the land, the Canaanites became a threat. This story warns the Israelites about the risk of being influenced by the Canaanites. Later, God commanded Israel not to marry or make deals with them because they were corrupt and would corrupt others. This chapter gives an implicit warning against adopting their lifestyle (34:1–2).

It also teaches Israel to maintain integrity and not misuse holy things for deceit or violence (34:13). Israel's reputation was at risk in the land (34:30). Because of their violent actions, Simeon and Levi did not receive the birthright blessing (49:5–7).
