'Afraid' in the Bible

The LORD then told Joshua, "Don't be afraid or lose heart! Take all the fighting men with you, and go up right now to Ai. Take note that I have handed over the king of Ai into your control, along with his people, his city, and his land.

But the LORD told Joshua, "Don't be afraid of them, because tomorrow about this time I am giving them all to you dead in the presence of Israel. Hamstring their horses and incinerate their chariots."
