“Yes, upon her children will I have no mercy, for they are children of whoredom; because their mother has played the harlot; she who conceived them has done shamefully.”
And the consequences of Israel's behaviour will be that her sons and daughters will suffer with her. They too will receive ‘no compassion' because they are the result of their mother's whoredom. The idea is ‘Like mother, like children'. She has ‘played the harlot' (Exodus 34:15-16; Deuteronomy 31:16) and behaved shamefully and the repercussions will come on those who follow (Exodus 34:16).
