'Afraid' in the Bible

Then said Saul to his armourbearer, Draw thy sword, and thrust me through therewith; lest these uncircumcised come and abuse me. But his armourbearer would not; for he was sore afraid. So Saul took a sword, and fell upon it.

And David was afraid of God that day, saying, How shall I bring the ark of God home 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 the LORD.
