Darby Translation

¹¹ and thou shalt slaughter the bullock before Jehovah, at the entrance of the tent of meeting;

¹² and thou shalt take of the blood of the bullock, and put it on the horns of the altar with thy finger, and shalt pour all the blood at the bottom of the altar.

¹³ And thou shalt take all the fat that covereth the inwards, and the net of the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar.
