The Meat Offering as a Wave Offering:
Numbers 8:13 “And you shall stand the Levites before Aaron and his sons, and then offer them like a wave offering to the Lord (in service).
15 The thigh of the heave offering and the breast of the wave offering they shall bring with the offerings of fat made by fire, to offer as a wave offering before the Lord. And it shall be yours and your sons’ with you, by a statute forever, as the Lord has commanded.”
Note: the heave offering was “lifted up” signifying Jesus having been”lifted up” on the cross.
The Sheaf Offering as a Wave Offering:
Leviticus 23:10-11 (NIV)
10 “Speak to the Israelites and say to them: ‘When you enter the land I am going to give you and you reap its harvest, bring to the priest a sheaf of the first grain (barley) you harvest. 11 He is to wave the sheaf before the Lord so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath
Why is this the only command which did not specify a specific day of the month but rather a day of the week?
It is because it is the day Jesus rose from the dead, the first day of the week when the women went to the tomb. It also meets the requirements of Jesus being in the heart of the earth for three days and three nights. The only year which fills all requirements is 31 AD.
See chart below:
Jesus, as the Lamb of God is the meat wave offering. Jesus, together with the saints whose tombs were opened are the sheaf wave offering. Jesus is the First Fruits.
The wave offerings represent resurrections. First Jesus, then the saints. A true resurrection is one where the person does not die again.
