'Go in Peace' in the Bible

Then Eli answered, "Go in peace; and may the God of Israel grant your petition that you have asked of him."

Yahweh do so to Jonathan, and more also, should it please my father to do you evil, if I don't disclose it to you, and send you away, that you may go in peace: and Yahweh be with you, as he has been with my father.

Jonathan said to David, "Go in peace, because we have both sworn in the name of Yahweh, saying, 'Yahweh shall be between me and you, and between my seed and your seed, forever.'" He arose and departed; and Jonathan went into the city.

Therefore now return, and go in peace, that you not displease the lords of the Philistines."
