'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 liking than the youths who are of your age? and ye would endanger my head with the king.

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

And he said 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 because of thy words.

and he said, Fear not, man greatly beloved; peace be unto thee, be strong, yea, be strong. And as he was speaking with me I was strengthened, and I said, Let my lord speak; for thou hast strengthened me.
