Jerome : "And she that was without mercy hath taken him away and conceived and brought forth a son. And he said: Call his name, Not my people: for you are not my people, and I will not be yours. " (The Septuagint likewise) And he who was called the seed of God, turned into a woman and, on account of the weakness of his strength and the offence against God, was led captive, not mentioned as having been weaned, but as having been weaned: for he had already lost his strength as a man. He who is weaned departs from his mother and does not feed on a parent's milk, but is sustained by external nourishment. Thus Israel, having been cast out by the Lord, and surrounded by the narrowness of captivity, and sustained with impure foods in Babylon, is called not the people of God, and an eternal sentence of a foreign people is carried, so that it is said, "You are not my people," and will be cast off forever. Which we can rightly understand in all the people of the Jews who, on account of the offense of the seed of God, were handed over to captivity, lost the kingdom and the province, and are called not the people of God; and also in the person of heretics. But if any contentious interpreter will not receive these things which we have said, but will understand that Gomer, the daughter of Deblaim, first bore male and female children, then male again, desiring the Scripture to sound what is read, let him answer how in Ezekiel he explains that where the Lord commands to bear the iniquities of the house of Israel, that is, of the ten tribes, and to sleep forever for three hundred and ninety days on one side of the left, although in the LXX they are written as one hundred and ninety, and to sleep so as never to wake up or change sides unless, perhaps, he satisfies his hunger by opening his eyes a little to take the most sordid food of bread baked from wheat, barley, beans, lentils, and millet in human excrement. For the nature of things does not allow that anyone among men should always sleep hidden for three hundred and ninety days in one place. And he says again: 'You will bear the iniquities of the house of Judah, and you will sleep on your right side for forty days.' But these days are calculated ((or were calculated)) as years, during which Israel and Judah are held by a very long siege and captivity, so that, bound and immobilized, they cannot turn from one side to the other. If it cannot approve of these things and others like them which we read in Holy Scripture, but argues that they signify something else, then this harlot and other adulterous women, who were either joined to prophets or were saved by a prophet, indicate not a shameful union of lust but the sacraments of the future. — Commentary on Hosea 1:8-9
