'Afraid' in the Bible

Then said Saul unto his armor-bearer, Draw thy sword, and thrust me through therewith, lest these uncircumcised come and abuse me. But his armor-bearer would not; for he was sore afraid. Therefore Saul took his 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 Jehovah.
