I. The measures of the altar, v. 13. It was six yards square at the top and seven yards square at the bottom; it was four yards and a half high; it had a lower bench or shelf, here called a settle, a yard from the ground, on which some of the priests stood to minister, and another two yards above that, on which others of them stood, and these were each of them half a yard broad, and had ledges on either side, that they might stand firmly upon them. The sacrifices were killed at the table spoken of before, ch. xl. 39. What was to be burnt on the altar was given up to those on the lower bench, and handed by them to those on the higher, and they laid it on the altar. Thus in the service of God we must be assistant to one another.
