The act of offering children to Molekh and passing them through fire – was common among pagans and is echoed in the story of Akeidat Yitzhak. It led to a perception that such practices had Divine legitimacy. Yirmiyahu emphasizes, in each of the three verses where the burning of children by fire is mentioned, that the act violates God’s command; that such an idea never “came into God’s mind,” and that God would never mislead His people this way. If indeed – as it appears from Yehezkel – the view prevailed among the people that this act was legitimate in God’s eyes, then it is clear why Yirmiyahu repeats over and over the prophetic message that there is no basis for it.
According to Yehezkel’s prophecy, the future revival of the nation will not come because of the covenant of the forefathers – which is not mentioned here at all – nor as the result of the nation repenting. It is a “forced” redemption, motivated by the desecration of God’s Name inherent in the very fact of the nation’s exile. The nation should therefore be ashamed of its deeds because of the Divine motivation to restore them to their land. This redemption is “forced” upon the people, as it were, with no opportunity for them to exercise their free choice – perhaps even against their will. It is for this reason that the whole nation will not return.
