'Encourage' in the Bible

Joshua the son of Nun, who standeth before thee, he shall go in thither: encourage thou him; for he shall cause Israel to inherit it.

But charge Joshua, and encourage him, and strengthen him; for he shall go over before this people, and he shall cause them to inherit the land which thou shalt see.

Then David said unto the messenger, Thus shalt thou say unto Joab, Let not this thing displease thee, for the sword devoureth one as well as another; make thy battle more strong against the city, and overthrow it: and encourage thou him.

They encourage themselves in an evil purpose; They commune of laying snares privily; They say, Who will see them?

In the day that I called thou answeredst me, Thou didst encourage me with strength in my soul.
