'Fear' in the Bible

The prince of the eunuchs said to Daniel, I fear my lord the king, who has appointed your food and your drink: for why should he see your faces worse looking than the youths who are of your own age? so would you endanger my head with the king.

I make a decree, that in all the dominion of my kingdom men tremble and fear before the God of Daniel; for he is the living God, and steadfast forever, His kingdom that which shall not be destroyed; and his dominion shall be even to the end.
