Parts of peace-offerings were so called, because they were waved by the priests ( Exodus 29:24,26,27 ; Leviticus 7:20-34 ; 8:27 ; 9:21 ; 10:14,15 , etc.), in token of a solemn special presentation to God. They then became the property of the priests. The first-fruits, a sheaf of barley, offered at the feast of Pentecost ( Leviticus 23:17-20 ), and wheat-bread, the first-fruits of the second harvest, offered at the Passover (10-14), were wave-offerings.
