The Prophet having spoken of the people's restoration, and promised that God would some time receive into favour those whom he had before rejected, now exhorts the faithful mutually to stir up one another to receive this favour. He had previously mentioned a public proclamation; for it is not in the power of men to make themselves the children of God, but God himself freely adopts them. But now the mutual exhortation of which the Prophet speaks follows the proclamation; for God at the same time invites us to himself. After we are taught in common, it remains then that each one should extend his hand to his brethren, that we may thus with one consent be brought together to the Lord. This then is what the Prophet means by saying, Say ye to your brethren, my omi, and to your sisters rvchmh ruchamah; that is, since I have promised to be propitious to you, you can now safely testify this to one another. We then see that this discourse is addressed to each of the faithful, that they may mutually confirm themselves in the faith, after the Lord shall offer them favour and reconciliation. Let us now proceed --

Say ye unto your brethren, Ammi - that is, "My people, and to your sisters, Ruhamah," i. e., "beloved or tenderly pitied." The words form a climax of the love of God. First, the people scattered , unpitied , and disowned by God , is re-born of God; then it is declared to be in continued relation to God, "My people;" then to be the object of his yearning love. The words, "My people," may be alike filled up, "ye are My people," and "be ye My people." They are words of hope in prophecy, "ye shall be again My people;" they become words of joy in each stage of fulfillment. They are words of mutual joy and gratulation, when obeyed; they are words of encouragement, until obeyed. God is reconciled to us, and willeth that we be reconciled to Him. Among those who already are God's people, they are the voice of the joy of mutual love in the oneness of the Spirit of adoption; "we are His people;" to those without (whether the ten tribes, or the Jews of heretics,) they are the voice of those who know in whom they have believed, "Be ye also His people." Despair of the salvation of none, but, with brotherly love, call them to repentance and salvation."
This verse closes what went before, as God's reversal of His own sentence, and anticipates what is to come (Hosea 5:14 ff). God commands the prophets and all those who love Him, to appeal to those who forget Him, holding out to them the mercy in store for them also, if they will return to Him. He bids them not to despise those yet alien from Him, "but to treat as brethren and sisters, those whom God willeth to introduce into His house, and to call to the riches of His inheritance."

Say ye unto your brethren, Ammi - I prefer the interpretation of these proper names. Say ye unto your brethren, My People; and, to your sisters, who have Obtained Mercy.

Say ye unto your (a) brethren, Ammi; and to your sisters, Ruhamah.
(a) Seeing that I have promised you deliverance, it remains that you encourage one another to embrace this promise, considering that you are my people on whom I will have mercy.

Say ye unto your brethren, Ammi; and to your sisters, Ruhamah. These words are to be considered either in connection with the latter part of the preceding chapter, and as directed to the sons of the living God, who had not been, but now were, "Ammi", the Lord's people; and who had not, but now have, "Ruhamah", obtained mercy; which grace and mercy shown them, it became them to speak of one to another, to affect their hearts mutually with it, and to glorify God for it, Malachi 3:16 as also to speak of it to their carnal relations, that so, if it was the will of God, it might be of use to them, to show them the state they were in, the danger of it, their need of the grace and mercy of God, and the hope there was by their own instance and example of obtaining it; see Romans 9:1, or as directed to the converted Jews that appointed Christ their Head, and believed in him; exhorting them to own the believing Gentiles as their brethren and sisters, since they were the spiritual seed of Abraham their father, and walked in the steps of his faith; and to call them Ammi and Ruhamah, since they, who were not the people of God, now were, and who had not obtained mercy, now have obtained mercy, 1-Peter 2:10, or else they may be considered as in connection with the following words,
plead with your mother; and that either as spoken to the two tribes of Judah and Benjamin, who were the people of God, retained the pure worship of God, and obtained mercy of the Lord, Hosea 1:7,
"O ye Ammi and Ruhamah, that are the Lord's people, and he has had mercy on; stir up and exhort your brethren and sisters of the ten tribes, for so they were, notwithstanding their separation, 1-Kings 12:4, to contend with their mother, the body of the nation, about idolatry and departure from God;''
or as spoken to the godly among the ten tribes, who were the real people of God, and sharers in his grace and mercy; the remnant he reserved for himself, who had not bowed their knees to idols; or as the command of God by the prophet, to the people of Israel, to exhort one another to contend with their mother, who were, as yet, the Lord's people, had mercy shown them, when this prophecy was delivered out; though, in case of obstinacy and impenitence, they were threatened with a "Loammi" and "Loruhamah"; so Schmidt, who thinks that "ammi" and "ruhamah" are put by way of "apposition to your brethren and sisters", in which he seems to be right. Aben Ezra thinks the words are spoken ironically, like those in Ecclesiastes 11:9, and others, but without reason. The Targum is,
"O ye prophets, say to your brethren, and my people, and I will have mercy on your congregation;''
but whether the words are spoken to the Jewish converts who first believed in Christ, were his people, received grace and mercy from him, and stood in the relation of brethren and sisters to one another, both in a natural and spiritual sense, to stir up one another to reprove their mother, the Jewish church, for rejecting Christ, saying, as follows:

This chapter continues the figurative address to Israel, in reference to Hosea's wife and children. Let us own and love as brethren, all whom the Lord seems to put among his children, and encourage them in that they have received mercy. But every Christian, by his example and conduct, must protest against evil and abuses, even among those to whom he belongs and owes respect. Impenitent sinners will soon be stripped of the advantages they misuse, and which they consume upon their lusts.

APPLICATION OF THE SYMBOLS IN THE FIRST CHAPTER. (Hosea. 2:1-23)
Israel's spiritual fornication, and her threatened punishment: yet a promise of God's restored favor, when chastisements have produced their designed effect.
Say . . . unto . . . brethren, Ammi, &c.--that is, When the prediction (Hosea 1:11) shall be accomplished, then ye will call one another, as brothers and sisters in the family of God, Ammi and Ruhamah.

To confirm the certainty of this most joyful turn of events, the promise closes with the summons in Hosea 2;Hosea 1:1-11 : "Say ye to your brethren: My people; and to your sisters, Favoured." The prophet "sees the favoured nation of the Lord (in spirit) before him, and calls upon its members to accost one another joyfully with the new name which had been given to them by God" (Hengstenberg). The promise attaches itself in form to the names of the children of the prophet. As their names of ill omen proclaimed the judgment of rejection, so is the salvation which awaits the nation in the future announced to it here by a simple alteration of the names into their opposite through the omission of the לא.
So far as the fulfilment of this prophecy is concerned, the fact that the patriarchal promise of the innumerable multiplication of Israel is to be realized through the pardon and restoration of Israel, as the nation of the living God, shows clearly enough that we are not to look for this in the return of the ten tribes from captivity to Palestine, their native land. Even apart from the fact, that the historical books of the Bible (Ezra, Nehemiah, and Esther) simply mention the return of a portion of the tribes of Judah and Benjamin, along with the priests and Levites, under Zerubbabel and Ezra, and that the numbers of the ten tribes, who may have attached themselves to the Judaeans on their return, or who returned to Galilee afterwards as years rolled by, formed but a very small fraction of the number that had been carried away (compare the remarks on 2-Kings 17:24); the attachment of these few to Judah could not properly be called a union of the sons of Israel and of the sons of Judah, and still less was it a fulfilment of the word, "They appoint themselves one head." As the union of Israel with Judah is to be effected through their gathering together under one head, under Jehovah their God and under David their king, this fulfilment falls within the Messianic times, and hitherto has only been realized in very small beginnings, which furnish a pledge of their complete fulfilment in the last times, when the hardening of Israel will cease, and all Israel be converted to Christ (Romans 11:25-26). It is by no means difficult to bring the application, which is made of our prophecy in 1-Peter 2:10 and Romans 9:25-26, into harmony with this. When Peter quotes the words of this prophecy in his first epistle, which nearly all modern commentators justly suppose to have been written to Gentile Christians, and when Paul quotes the very same words (Hosea 2:1, with Hosea 1:10) as proofs of the calling of the Gentiles to be the children of God in Christ; this is not merely an application to the Gentiles of what is affirmed of Israel, or simply the clothing of their thoughts in Old Testament words, as Huther and Wiesinger suppose, but an argument based upon the fundamental thought of this prophecy. Through its apostasy from God, Israel had become like the Gentiles, and had fallen from the covenant of grace with the Lord. Consequently, the re-adoption of the Israelites as children of God was a practical proof that God had also adopted the Gentile world as His children. "Because God had promised to adopt the children of Israel again, He must adopt the Gentiles also. Otherwise this resolution would rest upon mere caprice, which cannot be thought of in God" (Hengstenberg). Moreover, although membership in the nation of the Old Testament covenant rested primarily upon lineal descent, it was by no means exclusively confined to this; but, from the very first, Gentiles also were received into the citizenship of Israel and the congregation of Jehovah through the rite of circumcision, and could even participate in the covenant mercies, namely, in the passover as a covenant meal (Exodus 12:14). There was in this an indirect practical prophecy of the eventual reception of the whole of the Gentile world into the kingdom of God, when it should attain through Christ to faith in the living God. Even through their adoption into the congregation of Jehovah by means of circumcision, believing Gentiles were exalted into children of Abraham, and received a share in the promises made to the fathers. And accordingly the innumerable multiplication of the children of Israel, predicted in Romans 9:10, is not to be restricted to the actual multiplication of the descendants of the Israelites now banished into exile; but the fulfilment of the promise must also include the incorporation of believing Gentiles into the congregation of the Lord (Isaiah 44:5). This incorporation commenced with the preaching of the gospel among the Gentiles by the apostles; it has continued through all the centuries in which the church has been spreading in the world; and it will receive its final accomplishment when the fulness of the Gentiles shall enter into the kingdom of God. And as the number of the children of Israel is thus continually increased, this multiplication will be complete when the descendants of the children of Israel, who are still hardened in their hearts, shall turn to Jesus Christ as their Messiah and Redeemer (Romans 11:25-26).

Ye - Who of no people are made a people, who were once unpitied, but now have obtained mercy. Your brethren - To those of the ten tribes, who are your brethren. Ammi - Let them know that yet they are the people of God, they are still within the covenant of their father Abraham, if they will as their father, walk with God, all shall be well.
