Hosea 2:4

They be the children of whoredoms - They are all idolaters; and have been consecrated to idols, whose marks they bear.

I will not have mercy upon her children - God visits the sins of the parents upon the children, until the entailed curse be cut off by repentance. God enforces His own word "lo-ruhamah, Unpitied," by repeating it here, "lo-arahem," "I will not pity." Reproaches, which fall upon the mother, are ever felt with special keenness. Whence Saul called Jonathan 1 Samuel 20:30, "Thou son of the perverse rebellious woman." Therefore, the more to arouse them, he says, "for they are the children of whoredoms," evil children of an evil parent, as John the Immerser calls the hypocritical Jews, "ye generation of vipers" Matthew 3:7. "This they were, from their very birth and swaddling-clothes, never touching any work of piety, nor cultivating any grace." As of Christ, and of those who, in Him, are nourished up in deeds of righteousness, it is said, "I was cast upon Thee from the womb; Thou art my God from my mother's belly;" so, contrariwise, of the ungodly it is said, "The wicked are estranged from the womb; they go astray as soon as they be born, speaking lies."

And as they who "live honestly, as in the day and in the light," are called "children of the day and of the light," so they who live a defiled life are called the "children of whoredores." : "To call them 'children of whoredoms' is all one with saying, that they too are incorrigible or unchangeable. For of such, Wisdom, after saying, 'executing Thy judgments upon them by little and little,' added immediately (Wisd. 12:10, 11), 'not being ignorant that thy were a naughty generation, and that their malice was bred in them, and that their cogitation would never be changed, for it was a cursed seed from the beginning." All this is here expressed briefly by this word, "that they are the children of whoredoms," meaning that their "malice" too was inbred, and that they, as much as the Ammorite and Hittite, were a "cursed seed." Nor yet, in so speaking, did he blame the nature which God created, but he vehemently reproves the abuse of nature, that malice, which cleaves to nature but was no part of it, was by custom changed into nature."
