'Afraid' in the Bible

Then said Saul to his armour-bearer, Draw thy sword, and thrust me through with it; lest these uncircumcised come and abuse me. But his armour-bearer would not; for he was much afraid. So Saul took the sword and fell on it.

And David was afraid of God that day, saying, How shall I bring the ark of God to me?

But David could not go before it to inquire of God; for he was afraid because of the sword of the angel of Jehovah.
