Charles Ellicott Commentary Judges 1:20

"And they gave Hebron unto Caleb, as Moses had spoken: and he drove out thence the three sons of Anak." — Judges 1:20 (ASV)

Hebron. See Joshua 14:12-15; Joshua 15:13–14.

As Moses said.Numbers 14:21.

It is remarkable that after this time Judah is only mentioned in Judges 10:9; Judges 15:10; Judges 20:18. The tribe produced no judge, with the possible exception of Ibzan , nor is it mentioned in the song of Deborah. Perhaps we may see a reason for this in the strength which had won for Judah so secure a position. On the other hand, their conduct towards Samson was of the most abject kind (Judges 15:13). “As the nation gained in settled position and command of the soil it lost in unity and strength of external action. Each tribe looked out for itself” (Ewald, ii. 264).
