'Dismayed' in the Bible

Did I not command you? Be strong and courageous! Do not fear or be dismayed, for Yahweh your God is with you {wherever you go}."

Then Yahweh said to Joshua, "Do not fear or be dismayed. Take {all the fighting men} with you {and go up immediately to Ai}. Look, I am giving into your hand the king of Ai, his city, and his land.

And Joshua said to them, "Do not be afraid or dismayed! Be strong and bold, for thus Yahweh will do to all your enemies whom you [are] about to fight.
