'Mightier' in the Bible

I will smite them with the pestilence, and disinherit them, and will make of thee a greater nation and mightier than they.

and now, come, I pray thee, curse for me this people, for it is mightier than I; it may be I prevail -- we smite it -- and I cast it out from the land; for I have known -- that which thou blessest is blessed, and that which thou cursest is cursed.'
