This is the birth of the future leader of Israel. Through him God delivers his people. But who would think the leader came from the tribe of Levi? Simeon and Levi (both sons of Jacob) have murdered all the men of Shechem (Genesis 34:25). When Jacob blessed his sons before his death, he cursed the anger of Simeon and Levi (Genesis 49:7), and he prophesied a leading position of Judah (Genesis 49:8). God often follows unexpected ways in the history of salvation.
1 Now a man from the house of Levi went and took as his wife a Levite woman.
