Genesis 31:52

This heap [be] witness
Agreeably to its name, which both he and Jacob gave unto it: and [this] pillar [be] witness:
which was set up for the same purpose: 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;
not that these were to be the boundaries of their respective countries; for neither of them at present were possessed of lands that reached hither, if of any at all; nor that it would be a breach of covenant to pass over or by those, from one country into another, but so as to do, or with an intent to do, hurt to each other.
