let it be for a witness

Here the word "witness" does not refer to a person, but it is used figuratively and refers to the covenant that Jacob and Laban are making. The covenant is spoken of as if it were a person who is there when they agree to act peacefully to one another. (See: rc://en/ta/man/jit/figs-personification)
