The children of Israel arose, and went up to Bethel, and asked counsel of God; and they said, Who shall go up for us first to battle against the children of Benjamin? Yahweh said, Judah [shall go up] first.
and the Lord said, Judah shall go up first: which tribe pitched their standard first about the tabernacle, and marched first in their journeys in the wilderness, and was ordered to go up first and fight the Canaanites, being a powerful and warlike tribe.
