Exodus 30:4

And two golden rings shalt thou make to it under the crown of it,.... The crown was on the top of the altar, at the edge of it all around; and just underneath it were two rings of gold, two on each side:

by the two corners thereof, upon the two sides of it shall thou make them; at each corner a ring, and at each side; the use of them follows:

and they shall be for places for the staves to bear it withal; these rings were for the staves to be put into when the altar was to be carried from place to place, as it was in the wilderness, during the travels of Israel there; and this signifies that Christ never leaves his people; when they are in the wilderness he is with them, interceding for them, providing all things necessary for their food, safety, and protection, Revelation 12:14.
