'Stronger' in the Bible

And the men who went up with him said, "We are not able to go up to the people because they [are] stronger than us."

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."
