'Go in Peace' in the Bible

Then Eli answered and said, Go in peace; and the God of Israel grant thy petition that thou hast asked of him.

Jehovah do so to Jonathan, and more also, should it please my father to do thee evil, if I disclose it not unto thee, and send thee away, that thou mayest go in peace: and Jehovah be with thee, as he hath been with my father.

And Jonathan said to David, Go in peace, forasmuch as we have sworn both of us in the name of Jehovah, saying, Jehovah shall be between me and thee, and between my seed and thy seed, for ever. And he arose and departed: and Jonathan went into the city.

Wherefore now return, and go in peace, that thou displease not the lords of the Philistines.
