The first words of this chapter some make the close of the foregoing chapter, and add them to the promises which we have here of the great things God would do for them. When they shall have appointed Christ their head, and centered in him, then let them say to one another, with triumph and exultation (let the prophets say it to them, so the Chaldee—Comfort you, comfort you, my people, is now their commission), "say to them, Ammi, and Ruhamah; call them so again, for they shall no longer lie under the reproach and doom of Lo-ammi and Lo-ruhamah; they shall now be my people again, and shall obtain mercy." God's spiritual Israel, made up of Jews and Gentiles without distinction, shall call one another brethren and sisters, shall own one another for the people of God and beloved of him, and, for that reason, shall embrace one another, and stir up one another both to give thanks for and to walk worthy of this common salvation which they partake of. Or rather, because the following words seem to have a coherence with these, these also are designed for conviction and humiliation. The mother (v. 2) seems to be the same with the brethren and sisters (v. 1), the church of the ten tribes, the body of the people, who were brethren, and in a special manner with the heads and leaders, who were as the mother by whom the rest were brought up and nursed. But who are the children that must plead with their mother thus? Either, 1. The godly that were among them, that witnessed against the iniquities of the times, let them boldly go on to bear their testimony against the idolatries and gross corruptions that prevail among them. Let those that had not bowed the knee to Baal reason the case with those that had, and endeavour to convince them with such arguments as are here put into their mouths. Note, Private persons may, and ought in their places, to appear and plead against the public profanations of God's name and worship. Children may humbly and modestly argue with their parents when they do amiss: Plead with your mother, plead, as Jonathan with Saul concerning David. Or, 2. The sufferers among them, that shared in the calamities of the times, let them not complain of God, let them not quarrel with him, nor lay the blame on him, as if he had dealt hardly with them, and not like a tender father. No; let them plead with their mother, and lay the fault on her, where it ought to be laid; compare Isa. l. 1. "For her transgressions is your mother put away; she may thank herself, and you may thank her for all your miseries." Let us see now how they must plead with her.
