Mr. Roboto...
You said, "by committing spiritual adultery, as she often did, Israel became a harlot, this is confirmed by the bible. There's a lot more in revelation that points to Israel/Jerusalem being Babylon the great, mother of the prostitutes."
The torah prescribes a sacrifice for the sin of adultry. (Lev. 19:20-22) if the woman is not freed. (God asked israel, "where is the certificate of your divorce?")
Though the prophets often called israel back to God, the priests didn't make a sacrifice for the sin of israel's adultry. The scriptures declared that God looked around and any one indivdual who practiced the truth became prey to those who practiced unrighteousness.
God asks, "am I not righteous to save?" And "my own right arm will sustain Me" Scripture says that God's Servant is the right arm of God...that the Servant receives His righteousness from God. Scripture goes on to say that this Servant's soul is made an atonement for sin/transgression. This Servant is God's own right arm that sustains His own righteousness to save BECAUSE israel doesn't recognise their sinful state. So, while it is absolutely true that God didn't COMMAND a man to be sacrificed for sin in the torah or anywhere else in scripture, the scriptures themselves declare that it pleased God to see His Servant willingly "see his soul travail on behalf of many" (in order to be delivered up as the sacrifice for the atonement of THEIR (israel's) sin.) The penalty for adultry without delivering the required sacrifice is death.
God saved many from the penalty of death by the sacrifice of His willing Servant whom He calls His own right arm. God is righteous to save even when man is blind to his need for salvation.
Israel didn't recognize Jesus from the OT scriptures for a few reasons. He was hidden from them as an arrow in a quiver, He was under the cover of God's hand and they hid their face from Him (didn't recognize or acknowledge
their own sin)...the NT says though He was sinless [like an arrow hitting the mark perfectly] He became sin.
The mother of all harlots would recognize and acknowledge that sacrifice has been made for sin (Jesus) betroth herself (bride) but she would continue in her sin.
