"And as he read, saying: Wo, wo, unto Jerusalem, for I have sseen thine abominations! Yea, and many things did my father read concerning Jerusalme--that is should be destroyed, and the inhabitants thereof; many should perish by the sword, and many should be carried away captive into Babylon."
Twice sayint wo emphasises that there were serious problems in Jerusalem. The Lord sees all the sins and iniquities of every person and by the Spirit can the prophet be sent to either guide or warn those what need the chance to repent. Thee abominations done were serious and defiled the sacred house of God in Jerusalem. This is a sin that is awful to contemplate. The things that could have been done in the house of God would have been severe.
By the prose and word of the Lord jerusalem was destroyed and the pople inside either killed or carried captive into Babylon. Through the words of the prophets and the power of the Lord Jerusalem was destroyed and the sins of it were cleansed.
The people that were not destroyed witht he city were taken captive by those who overcame the land.. The king himself was taken as well and the words of the Lord came true as they always will.
