'Fear' in the Bible

That all the people of the earth might know the hand of the LORD, that it is mighty: that ye might fear the LORD your God for ever.

And the LORD said unto Joshua, Fear not, neither be thou dismayed: take all the people of war with thee, and arise, go up to Ai: see, I have given into thy hand the king of Ai, and his people, and his city, and his land:

And the LORD said unto Joshua, Fear them not: for I have delivered them into thine hand; there shall not a man of them stand before thee.

And Joshua said unto them, Fear not, nor be dismayed, be strong and of good courage: for thus shall the LORD do to all your enemies against whom ye fight.

And if we have not rather done it for fear of this thing, saying, In time to come your children might speak unto our children, saying, What have ye to do with the LORD God of Israel?

Now therefore fear the LORD, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the LORD.
