3 yes, he loved the people; all his saints in your hand: and they sat down at your feet; shall receive of your words.

4 Moses commanded us a law, the inheritance of the congregation of Jacob.

5 And he was king in Jeshurun, when the heads of the people the tribes of Israel were gathered together.

6 Let Reuben live, and not die; and let his men be few.
