Genesis

⁴⁶And Jacob said unto his brethren, Gather stones; and they took stones, and made an heap: and they did eat there by the heap. ⁴⁷And Laban called it Jegar-sahadutha: but Jacob called it Galeed. ⁴⁸And Laban said, This heap is 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, and if thou shalt take 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 the pillar, which I have set betwixt me and thee. ⁵²This heap be witness, and the 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.
