There are several examples in Genesis that the second-born was blessed in stead of the first-born.
For instance, Isaac, Jacob and Ephraim were blessed in stead of Ishmael, Essau and Manasseh.
The first-born represents Flesh and the second-born represents Spirit.
Flesh represents Disbelief, Disobedience and Destruction, but Spirit represents Faith, Obedience and Completion.
This is why Jesus is called as the second Adam(the last Adam).
Israel is the first-born and the Gentile Church(the Philadelphia Church) is the second-born.
This principle of God can apply for two stone tablets of Moses.
According to the Midrash, Elul 1 was the day when Moses went up to God to receive the second tablets.
As it's written in Colossians 2:16-17, the New Moon is a shadow of thing to come.This Scripture must be fulfilled.Also the New Moon is called as the Veiled Moon."And we all, who with unveiled faces contemplate the Lord's glory, are being transformed into his image withever-increasing glory, which comes from the Lord, who is the Spirit" (2 Corinthians 3:18)And the month of Elul is known for Song of Songs 6:3."I am my beloved's, and my beloved is mine"Therefore, it's very possible that the Bride of the Philadelphia Church is taken to the Throne of God on Elul 1.If not, keep watching!Maranatha!
