TSK · Exodus 27:2

And therewith he made the sockets to the door of the tent of meeting, and the brazen altar, and the brazen grating for it, and all the vessels of the altar,

And he shall put of the blood upon the horns of the altar which is before Jehovah, that is in the tent of meeting; and all the blood shall he pour out at the base of the altar of burnt-offering, which is at the door of the tent of meeting.

And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured out the blood at the base of the altar, and sanctified it, to make atonement for it.

even the censers of these sinners against their own lives; and let them be made beaten plates for a covering of the altar: for they offered them before Jehovah; therefore they are holy; and they shall be a sign unto the children of Israel.

And the tidings came to Joab; for Joab had turned after Adonijah, though he turned not after Absalom. And Joab fled unto the Tent of Jehovah, and caught hold on the horns of the altar.

Jehovah is God, and he hath given us light: Bind the sacrifice with cords, even unto the horns of the altar.
