Laban adds another significance to the heap of witness and binds Jacob with an oath not, in the future, to go past this heap of witness with the aim of doing Laban harm. It is as if a man intent on justifying himself can never do enough, for his conscience is still troubling him.
All these things are written for our admonition upon whom the end of the age, the end of the world, are come. We draw the principal from this account that when you serve the Lord, and when you love him, and when you follow him, you engage in no compromise at all. Today we have light from the Old Testament and from the New Testament, so we do not say, ‘It is safe for us to borrow from the culture of the world. Jacob adopted the practices of the world in taking two wives, and their maidservants, and that was acceptable.’ Scripture points out all the trouble that came from this decision in order to teach us. There are good people all over the world who have been bamboozled into adopting worldly culture. But now God delivers Jacob out of it. It is the constantly repeated story of Genesis. The world comes, and God to teach us delivers his people who are going to bring forth the Saviour, out of it, and yet again in these chapters, you see the same event being repeat.
