But go rather to the lost sheep The first rank, as we have said, is assigned to the Jews, because they were the firstborn; or rather, because at that time they alone were acknowledged by God to belong to his family, while others were excluded. [1] He calls them lost sheep, partly that the apostles, moved by compassion, may more readily and with warmer affection run to their assistance, and partly to inform them that there is at present abundant occasion for their labors. At the same time, under the figure of this nation, Christ taught what is the condition of the whole human race. The Jews, who were near to God, and in covenant with him, and therefore were the lawful heirs of eternal life, are nevertheless pronounced to be lost, till they regain salvation through Christ. What then remains for us who are inferior to them in honor? [2] Again, the word sheep is applied even to the reprobate, who, properly speaking, did not belong to the flock of God, because the adoption extended to the whole nation; as those who deserved to be rejected, on account of their treachery, are elsewhere called the children of the kingdom, (Matthew 8:12.) In a word, by the term sheep, Christ recommends the Jews to the apostles, that they may dedicate their labors to them, because they could recognize as the flock of God none but those who had been gathered into the fold.

But go rather to the lost sheep - That is, to the Jews. He regarded them as wandering and lost, like sheep straying without a shepherd. They had been the chosen people of God; they had long looked for the Messiah; and it was proper that the gospel should be first offered to them.
But go rather to the lost sheep, etc. - The Jewish Church was the ancient fold of God; but the sheep had wandered from their Shepherd, and were lost. Our blessed Lord sends these under-shepherds to seek, find, and bring them back to the Shepherd and Overseer of their souls.
But go rather to the lost sheep of the house of Israel. To whom he himself was sent, Matthew 15:24. By "the house of Israel" is meant the whole Jewish nation; for though this phrase, when distinguished from the house of Judah, designs only the ten tribes; yet here it intends all the Jews, then living in the land of Judea, among whom there were some of all the tribes: and by "the lost sheep" of this house, are meant either all the people of the Jews in general, who were wandering, and were lost in error and sin, and to whom the external ministry of the Gospel came; or rather the elect of God among them, for whose sake particularly the apostles were sent unto them. These are called "sheep", because they were chosen of God, and given to Christ to be redeemed, looked up, sought out, and saved by him; and "lost" ones, not only because lost in Adam, and by their own transgressions, so that neither they themselves, nor any mere creature, could save them from eternal ruin and destruction; but also, because they were made to go astray, and were lost through the negligence and errors of their pastors, the Scribes and Pharisees: and this character is the rather given of them, partly to reflect upon the characters of the shepherds of Israel: and partly to magnify the grace of God, in having regard to such ruined and miserable creatures; and also to excite the compassion and diligence of the apostles, to preach the Gospel to them: respect seems to be had to Jeremiah 1:16.
But go rather to the lost sheep of the house of Israel--Until Christ's death, which broke down the middle wall of Partition (Ephesians 2:14), the Gospel commission was to the Jews only, who, though the visible people of God, were "lost sheep," not merely in the sense which all sinners are (Isaiah 53:6; 1-Peter 2:25; compare with Luke 19:10), but as abandoned and left to wander from the right way by faithless shepherds (Jeremiah 50:6, Jeremiah 50:17; Ezekiel 34:2-6, &c.).
