Thematic Bible: By a monument

"And this toot-hill which the LORD seeth," said he, "be witness between me and thee when we are departed one from another: that thou shalt not vex my daughters neither shalt take other wives unto them. Here is no man with us: behold, God is witness betwixt thee and me." And Laban said moreover to Jacob, "Behold, this heap and this mark which I have set here, betwixt me and thee: read more.
this heap be witness and also this mark, that I will not come over this heap to thee, and thou shalt not come over this heap and this mark, to do any harm. The God of Abraham, the God of Nahor, and the God of their fathers, be judge betwixt us." And Jacob sware by him that his father Isaac feared.
