6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
"At night, I made your mother be silent, my people have become silent, because they have no knowledge: for you have rejected knowledge, I will reject you, and you will not serve as a priest to me; and you have forgotten the law of your God, I will also forget your sons." LXX: "I have compared thy mother to the night, and my people to have no knowledge. Since thou hast refused knowledge, I will also refuse thee, that thou shalt not be a priest to me. Thou hast forgotten the law of thy God, and I will forget thy children." Not because there are other mothers and other sons, does she call herself mother and sons; but just as the Lord spoke to the Jewish people and said, "Jerusalem, Jerusalem, thou that killest the prophets and stonest those sent to thee, how often I have desired to gather thy children together, as a hen gathers her chicks under her wings, and thou didst not want it." (Matthew 23, 5). Not as another Jerusalem, and another people thereof: for it did not speak without the people to the building of the city and the wood and the stones. Thus the mother is called the crowd of the people and every multitude of the Hebrew nation, to whom it speaks: but the sons, either single or dispersed through the towns and villages of the people. Therefore in the night and darkness of captivity, mourning and pressing distress, Israel is surrendered and its people remain silent in eternal silence; because it did not have knowledge of the law, nor did it keep the commandments of God, and received what it had done. For she herself has rejected God's law, and thus she has lost the priesthood forever, and worships the golden calves in Dan and Bethel; and because she has forgotten God's law, and entirely enslaved herself to Egyptian idols, therefore the Lord will also forget her children, delivering them to eternal captivity: "For he who is ignorant, let him be ignorant." (I Cor. XIV), and in the Psalms we read: "They did not know, nor did they understand, they walked in darkness." (Ps. LXXXI, 5). We can refer everything that is said about the ten tribes to the heretics who have left the kingdom of David and Jerusalem, that is, Christ and the Church: and therefore they are covered with eternal night, they do not have the knowledge of God, and they are rejected by the Lord so that they may not perform the priesthood to him, and they never remember the children they have generated, because they have become aliens to him.
