'Fear' in the Bible

And the prince of the eunuchs said unto Daniel, I fear my lord the king, who hath appointed your food and your drink: for why should he see your faces worse looking than the youths that are of your own age? so would ye 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 stedfast for ever, And his kingdom that which shall not be destroyed; and his dominion shall be even unto the end.

Then said he unto me, Fear not, Daniel; for from the first day that thou didst set thy heart to understand, and to humble thyself before thy God, thy words were heard: and I am come for thy words'sake.

And he said, O man greatly beloved, fear not: peace be unto thee, be strong, yea, be strong. And when he spake unto me, I was strengthened, and said, Let my lord speak; for thou hast strengthened me.
