G-d didnt have that plan...ever. That is an invention of the Grecco-Roman church. It is a leftover from the teachings of gods coming to earth, having mortal wives and demi-god children. The church teaching of Jesus being 100%god and 100% man is an offshoot of this Grecco-Roman mythology.
Don’t tell me, tell it to God,..He is the one you have to convince.
Actually Genesis Chapter 3:15 foretold the virgin birth......”“Cursed are you above all livestock
and all wild animals!
You will crawl on your belly
and you will eat dust
all the days of your life.
15 And I will put enmity
between you and the woman,
and between your offspring[a] and hers;
he will crush[b] your head,
and you will strike his heel.”
The KJV calsl it “her seed”, the only time in the OT where a woman is referred to having “seed” without a man involved.
Moses himself prophesied of a “Star arising out of Jacob” meaning that despite the Laws and statutes God had revealed to Moses, Moses knew that an even greater revelation of God’s love was going to be revealed thru one of the future descendents of Jacob.
