'Lawgivers' in the Bible

The fountain made by the chiefs, made deep by the great ones of the people, with the law-givers' rod, and with their sticks. Then from the waste land they went on to Mattanah:

My heart is to the lawgivers of Israel, Who are offering themselves willingly among the people, Bless ye Jehovah!

Out of Ephraim their root is against Amalek. After thee, Benjamin, among thy peoples. Out of Machir came down lawgivers, And out of Zebulun those drawing with the reed of a writer.

To give his chiefs teaching at his pleasure, and so that his law-givers might get wisdom from him.
