Judges 1:2

The Lord said, Judah shall go up - They had inquired of the Lord by Phinehas the high priest; and he had communicated to them the Divine counsel.

And the Lord said - i. e. answered by Urim and Thummim. The land was the portion which fell to Judah by lot, not the whole land of Canaan (see Judges 3:11). The priority given to Judah is a plain indication of divine direction. It points to the birth of our Lord of the tribe of Judah. Judah associated Simeon with him Judges 1:3 because their lots were intermingled Joshua 19:1.

1:2 Judah - The tribe of Judah is chosen for the first enterprise, because they were both most populous, and so most needing enlargement; and withal most valiant, and therefore most likely to succeed: for God chooseth fit means for the work which he designs. Moreover the Canaanites were numerous and strong in those parts, and therefore to be suppressed, before they grew too strong for them.
