'Fearing' in the Bible

And Saul said to Samuel, Great is my sin: for I have gone against the orders of the Lord and against your words: because, fearing the people, I did what they said.

And David took these words to heart, fearing Achish, the king of Gath.

Not one living man or woman did David ever take back with him to Gath, fearing that they might give an account of what had taken place, and say, This is what David did, and so has he been doing all the time while he has been living in the land of the Philistines.
