Judges 5:14-15

14From Ephraim their root they marched down into the valley, following you, Benjamin, with your kinsmen; from Machir marched down the commanders, and from Zebulun those who bear the lieutenant's staff;

15the princes of Issachar came with Deborah, and Issachar faithful to Barak; into the valley they rushed at his heels. Among the clans of Reuben there were great searchings of heart.
