Judges 1:2

The Lord said. — The answer is given to the priest by the Urim, and he announces it to the people.

Judah shall go up. — The phrase “go up” is used in a military sense (Joshua 6:5). The question had not been, “Who shall be our leader?” but, “Which tribe shall fight first?” The reason why Judah is chosen is from the eminence and power of the tribe, which was also the most numerous at both of the censuses taken in the wilderness (Numbers 1:26; Numbers 26:19). Jacob’s blessing on the tribe had been, “Judah, thou art he whom thy brethren shall praise: thy hand shall be in the neck of thine enemies” (Genesis 49:8). (Comp. Numbers 34:19; Joshua 15:1.) In the arrangement of the camp, Judah was stationed at the east, with Issachar and Zebulon, and always started first on the march (Numbers 2:3), with its lion-standard, which was a symbol of its lion-courage (Genesis 49:9; Revelation 5:5). The same answer is given by Urim in Judges 20:18.
