'Be Strong' in the Bible

and see the land, what manner thing it is; and the people that dwelleth therein, whether they be strong or weak, either few or many;

And what the land, whether it is fat or lean, whether there is in it wood or not And be strong, and take from the fruit of the land. And the days, the days of the first-fruits of the grapes.

Nevertheless, the people be strong that dwell in the land, and the cities are walled and exceeding great, and moreover we saw the children of Anak there.

Come now, in answer to my prayer, and put a curse on this people, for they are greater than I: and then I may be strong enough to overcome them and send them out of the land: for it is clear that good comes to him who has your blessing, but he on whom you put your curse is cursed.
