Targum sobre Números 22:24

And the angel of the Lord stood in a narrow path that was in the midst between vineyards, in the place where Jacob and Laban raised the mound, the pillar on this side and the observatory on that side, which they raised, that neither should pass that limit to do evil (to the other).

And the angel of the Lord stood between the vineyards, a hedge (being) on this and on that side.
