¹⁴ Then he brought the bull for the sin offering. Aaron and his sons placed their hands on its head. ¹⁵ Moses killed the bull. He dipped his finger into some of the blood. He put it on the horns that stick out from the upper four corners of the altar. He did it to make the altar pure. He poured out the rest of the blood at the bottom of the altar. So he set it apart to make it pure. ¹⁶ Moses also removed all the fat around the inside parts of the bull. He removed the long part of the liver. He took both kidneys and their fat. Then he burned all of it on the altar.
