'Witness' in the Bible

So now, come, let us {make} a covenant, you and I, and let it be a witness between me and you."

Then Laban said, "This pile of stones [is] a witness between me and you today." Therefore its name is called Galeed,

If you mistreat my daughters, and if you take wives besides my daughters, [when] there is no man with us, see--God [is] a witness between me and you."

This pile of stones [is] a witness, and the pillar [is] a witness, that I will not pass beyond this pile of stones to you, and that you will not pass beyond this pile of stones and this pillar to me intending harm.
