Genesis 31:48

44Now therefore come thou, let us make a covenant, I and thou; and let it be for a witness between me and thee.

45And Jacob took a stone, and set it up for a pillar.

46And Jacob said unto his brethren, Gather stones; and they took stones, and made an heap: and they did eat there upon the heap.

47And Laban called it Jegar–sahadutha: but Jacob called it Galeed.

48And Laban said, This heap is a witness between me and thee this day. Therefore was the name of it called Galeed;

49And Mizpah; for he said, The Lord watch between me and thee, when we are absent one from another.

50If thou shalt afflict my daughters, or if thou shalt take other wives beside my daughters, no man is with us; see, God is witness betwixt me and thee.

51And Laban said to Jacob, Behold this heap, and behold this pillar, which I have cast betwixt me and thee;

52This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm.
