'Stronger' in the Bible

But the men that went up with him said, We be not able to go up against the people; for they are stronger than we.

I will strike them with disease, and I will dispossess them; I will make you into a greater and stronger nation than them."

Now, please go, curse this people for me because they [are] stronger than me; perhaps I will be able to strike them and drive them out from the land because I know whoever you bless [is] blessed, and whoever you cursed is cursed."
