29 “Tell the Israelites, ‘Whoever presents his communion sacrifice to Jehovah will bring part of the offering from his communion sacrifice to Jehovah.+ 30 He will bring in his own hands the fat+ along with the breast as an offering made by fire to Jehovah, and he will wave it back and forth as a wave offering+ before Jehovah. 31 The priest will make the fat smoke on the altar,+ but the breast will belong to Aaron and his sons.+
