John Gill Commentary Acts 13:19

"And when he had destroyed seven nations in the land of Canaan, he gave [them] their land for an inheritance, for about four hundred and fifty years:" — Acts 13:19 (ASV)

And when he had destroyed seven nations in the land of
Canaan
The Canaanites, Hittites, Amorites, Perizzites, Hivites, Jebusites, and Girgashites; and the name of seven nations is what they are usually called by in Jewish writings; and though they were not utterly destroyed, or everyone of them put to death, or driven out, for some remained to be thorns in the sides of the Israelites; yet they were so wasted and conquered, that they could never recover any more.

He divided their land to them; every tribe had its portion of it assigned, by lot; see (Joshua 14:1–3) .
