'Wider' in the Bible

These are the words of the Lord: For three crimes of the children of Ammon, and for four, I will not let its fate be changed; because in Gilead they had women with child cut open, so that they might make wider the limits of their land.

Go on to Calneh and see; and from there go to Hamath the great; then go down to Gath of the Philistines: are you better than these kingdoms? or is your land wider than theirs?
