'Mightier' in the Bible

dispossessing and driving out from before you nations, [nations that were] greater and mightier than you, to bring you in, to give you their land as an inheritance, as it is this day.

“When the Lord your God brings you into the land which you are entering to possess, and has cleared away many nations before you, the Hittite and the Girgashite and the Amorite and the Canaanite and the Perizzite and the Hivite and the Jebusite, seven nations greater and mightier than you,

“Hear, O Israel! You are crossing the Jordan today to go in to dispossess nations greater and more powerful than you, great cities fortified to heaven,

Let Me alone, so that I may destroy them and wipe out their name from under heaven; and I will make of you a nation mightier and greater than they.’

then the Lord will drive out all these nations from before you, and you shall dispossess nations greater and mightier than you.
