'Go in Peace' in the Bible

Then Eli answered and said, “Go in peace; and may the God of Israel grant your petition that you have asked of Him.”

Jonathan told David, “Go in safety, inasmuch as we have sworn to each other in the name of the Lord, saying, ‘The Lord shall be between me and you, and between my descendants and yours forever.’” Then he stood and left, while Jonathan went into the city.
