3 Judah said to Simeon his brother, "Come up with me into my lot, that we may fight against the Canaanites; and I likewise will go with you into your lot." So Simeon went with him.

Come up with me into my lot - It appears that the portions of Judah and Simeon had not been cleared of the Canaanites, or that these were the parts which were now particularly invaded.
And Judah said unto Simeon his (c) brother, Come up with me into my lot, that we may fight against the Canaanites; and I likewise will go with thee into thy lot. So Simeon went with him.
(c) For the tribe of Simeon had their inheritance within the tribe of Judah, (Joshua 19:1).
And Judah said unto Simeon his brother,.... The men of the tribe of Judah said to those of the tribe of Simeon, they being not only brethren by father's and mother's side, which was not the case of all the sons of Jacob, but their possessions and inheritances lay near together; and indeed those of Simeon were within the inheritance of the tribe of Judah, Joshua 19:1; so that as they lived in great nearness and familiarity with each other, their interests were closely united together:
come up with me into my lot, that we may fight against the Canaanites; conjunctly: the meaning is, that the tribe of Simeon, as many of their warlike men as could, would come and join their forces with those of the tribe of Judah, in order to reduce such cities, in the lot of that tribe, the Canaanites as yet were in the possession of:
and I likewise will go with thee into thy lot: the cities being conquered which were in the lot, of the tribe of Judah, that tribe proposed to bring their united forces into the lot of the tribe of Simeon, and reduce such cities as were in that lot:
so Simeon went with him: the tribe of Simeon agreed to the proposal, and went along with the tribe of Judah against their common enemy.
Judah said unto Simeon his brother, Come up with me . . ., that we may fight against the Canaanites--Being conterminous tribes (Joshua 19:1-2), they had a common interest, and were naturally associated in this enterprise.
Judah invited Simeon his brother, i.e., their brother tribe, to take part in the contest. The epithet is applied to Simeon, not because Simeon and Judah, the sons of Jacob, were the children of the same mother, Leah (Genesis 29:33, Genesis 29:35), but because Simeon's inheritance was within the territory of Judah (Joshua 19:1.), so that Simeon was more closely connected with Judah than any of the other tribes. "Come up with me into my lot (into the inheritance that has fallen to me by lot), that we may fight against the Canaanites, and I likewise will go with thee into thy lot. So Simeon went with him," i.e., joined with Judah in making war upon the Canaanites. This request shows that Judah's principal intention was to make war upon and exterminate the Canaanites who remained in his own and Simeon's inheritance. The different expressions employed, come up and go, are to be explained from the simple fact that the whole of Simeon's territory was in the shephelah and Negeb, whereas Judah had received the heart of his possessions upon the mountains.
To Simeon - As nearest to him both by relation, being his brother by both parents, and by habitation. The Canaanites - Specially so called, because they are distinguished from the Perizzites, Judges 1:4.
