ALTAR FOR BURNT OFFERING. (Exo. 27:1-21) altar of shittim wood--The dimensions of this altar which was placed at the entrance of the sanctuary were nearly three yards square, and a yard and a half in height. Under the wooden frame of this chest-like altar the inside was hollow, and each corner was to be terminated by "horns"--angular projections, perpendicular or oblique, in the form of horns. The animals to be sacrificed were bound to these (Psa 118:27), and part of the blood was applied to them.
