Charles Ellicott Commentary Exodus 26:32

"And thou shalt hang it upon four pillars of acacia overlaid with gold; their hooks [shall be] of gold, upon four sockets of silver." — Exodus 26:32 (ASV)

Four pillars. — These seem to have been true pillars or columns, and not tent-poles. They were probably of equal height, and equally spaced, and were perhaps connected at the top by a cornice or beam. Together with the veil they formed a screen, which shut off the “Holy of Holies” from the outer chamber. They were, doubtless, of the same height as the boards, that is, fifteen feet (Exodus 26:16).

Their hooks. — Each pillar was to have a hook near the top, to which the veil was to be attached.

Upon the four sockets. — Hebrew: upon four sockets. — Each pillar was to have its “socket,” into which it was to be inserted, and which was itself probably to be sunk into the ground.
