Hosea 2:4

“And I will not have mercy upon her children, etc.] The posterity of the Jews in succeeding ages, until the time of their conversion comes; they persisting in the sins of their forefathers, filling up the measure of their iniquities; remaining in their obstinate rejection of the Messiah, and in the same impenitence and unbelief, and having his blood imprecated upon them: for they be the children of whoredoms; begotten and born in whoredom, spurious and illegitimate; or that commit whoredoms; imitate their parents; are guilty of the same vices; a generation of vipers.
