Benjamin's Blessing
This is the second favorite son so you might expect a little bit more out of Jacob. Being left-hand, they were hard to kill in battle, and were good archers.
Wiersbe writes: You would expect Jacob to say more to and about his youngest son Benjamin, the “son of his right hand,” but his words were few and puzzling. Why compare Benjamin to a “ravenous wolf”? The men of Benjamin were brave and helped defeat Sisera (Judges 5:14), but when you read Benjamin’s tribal history in Judges 19 and 20, you see the ravenous wolf in action. Saul, the first king of Israel, was from Benjamin. During his career, he more than once tried to kill David (1 Samuel 19:10), and he ruthlessly murdered everybody in the priestly city of Nob (1 Samuel 22:6ff). Other Benjamites known for their ferocity were Abner (2 Samuel 2:23), Sheba (chap. 20), and Shimei (2 Samuel 16:5–14). Saul of Tarsus, a Benjamite (Romans 11:1; Philippians 3:5) was like a wild animal when he persecuted the church and tracked down Christians to imprison them.
It’s remarkable that Moses’ words about Benjamin say nothing about the ferocious behavior of an animal (Deuteronomy 33:12). Instead, Moses called him “the beloved of the Lord” and promised him constant protection from God. In fact, Benjamin shall “dwell between His shoulders,” which suggests either being carried on his back or over his heart. When the nation divided after Solomon’s death, the tribe of Benjamin remained faithful to the Davidic line and stayed with Judah. Together they formed the Southern Kingdom of Judah.
Genesis 49:27New American Standard Bible: 1995 Update
“Benjamin is a ravenous wolf;
In the morning he devours the prey,
And in the evening he divides the spoil.”
