'Go in Peace' in the Bible

And Eli answereth and saith, 'Go in peace, and the God of Israel doth give thy petition which thou hast asked of Him.'

and Jonathan saith to David, 'Go in peace, in that we have sworn -- we two -- in the name of Jehovah, saying, Jehovah is between me and thee, and between my seed and thy seed -- unto the age;' and he riseth and goeth; and Jonathan hath gone in to the city.

and now, turn back, and go in peace, and thou dost do no evil in the eyes of the princes of the Philistines.'
