623. Being firstfruits to God and to the Lamb. This symbolizes the commencement of a Christian heaven that acknowledges one God, in whom is the Trinity, and acknowledges that the Lord is that one.
Firstfruits mean something that is produced first, and something gathered first, thus a commencement, here the commencement of a new heaven formed of Christians. God and the Lamb mean here, as before, the Lord in respect to the Divine itself from which springs all else, and in respect to His Divine humanity, including the emanating Divinity, thus one God in whom is the Trinity.
We will say something here about firstfruits. In the Israelite Church people were commanded to give to Jehovah as sacred the firstfuits of produce - of every kind of grain, of oil and wine, of the fruits of trees, and of wool - and these were given by Jehovah to Aaron, and after him to the high priest (Exodus 22:29; 23:19, Numbers 13:20; 15:17-21; 18:8-20, Numbers 28:26-31).
The reason for this was that firstfruits symbolized something that is produced first and afterward grows, like a child into an adult, or a cutting into a tree, and thus it symbolized every subsequent development until the thing's completion. For every subsequent development is present in the initial one, like the adult in the child, or the tree in the cutting. And because this first development occurs before the subsequent ones, as is the case also in heaven and in the church, therefore the firstfruits were sacred to the Lord, and the people celebrated a feast of firstfuits.
Firstfruits have a similar symbolic meaning in Jeremiah 24:1-2, Ezekiel 20:40, Micah 7:1, Deuteronomy 33:15, 21.
Deuteronomy 18:4, 26:1; Exodus 23:26, 23:14-16, 23:10; Leviticus 23:20-25, 23:10, 23:9-15; Numbers 15:17-22; Revelation 14:4)
