Judges 1:18-20

18 And Judah captured Gaza with the boundaries thereof, and Ashkelon, with the boundaries thereof, and Ekron, with the boundaries thereof.

19 And it same to pass that Yahweh was with Judah, and he took possession of the hill country, but did not dispossess the inhabitants of the vale, because they had, chariots of iron.

20 So they gave unto Caleb Hebron, as spake Moses, and he drave out from thence the three sons of Anak.
