5Then one of the priests will burn those things on the altar, along with the other parts of the animal that will be completely burned to be an offering to Yahweh. And the aroma while it burns will be pleasing to Yahweh.
6If that offering to maintain good fellowship with Yahweh is a sheep or a goat, it must also be an animal that has no defects.
7If you offer a lamb, you must present it to Yahweh at the entrance to the Sacred Tent. You must lay your hands on the lamb's head and then slaughter it. You must drain some of its blood in a bowl.
8Then one of the priests will sprinkle that blood against all sides of the altar.
9You must dedicate these things to be a sacrifice to Yahweh that is burned: Its fat, the fat tail that you must cut off close to the backbone, and all the fat that covers the inner parts of the lamb or which is attached to them—
