Joel 3:7

Behold, I will raise them out of the place whither ye have sold them, and will return your recompence upon your own head:

Ver. 7. Behold, I will raise them out of the place, &c.] Seem it never so improbable or impossible, I will do it, saith God, and you shall see it. Behold, I will fetch home my banished, though they may seem to be as water spilt on the ground. I will make those dead bones live; and raise myself a name, and a praise, by outbidding their hopes, and marring your design of utter extermination. Ribera understands the words concerning the resurrection of the dead at the last day, because the Hebrew word properly signifieth, to raise one out of sleep. Some think it is meant of the apostles and martyrs, fetched out of banishment; as was John out of Patmos, Athanasius, Chrysostom, who yet in his last banishment, by reason of the barbarous usage of the soldiers that led him along, hired for that purpose, sweetly and blessedly breathed out his last, (Erasm. in Vita Chrysost.), the English exiles in Queen Mary's time, whereof many returned and did excellent service here. But I doubt not, saith judicious Calvin (in loc.), but God intends here a spiritual gathering together of his people into one body, by the bond of faith; and this was principally fulfilled after the death of Christ, who died for that nation, "And not for that nation only, but that also he should gather together into one the children of God that were scattered abroad," John 11:52; so that those whom God hath gathered together and caused to return (non pedibus vel navigio, for that needs not, to Jerusalem, which is above, which is the mother of us all), from the lands of the east, of the west, of the north, and of the south, shall praise the Lord together, as the psalmist hath it, Psalms 107:2,3 .

And will return your recompence upon your own head] God delights to retaliate, to bloody and deceitful men especially; as were easy to instance in the Egyptians, Adonibezek, Agag, Attilius Regulus, the Roman general, who dealt most cruelly with the Carthaginians, and was shortly after as cruelly dealt with by them, when fallen into their hands (Polybius). Here at home, in King Edward VI's time, the remembrance of Somerset much moved the people to fall from Northumberland (who had wrought his death) in his greatest attempts, and to leave him to his fatal fall; whereas also they openly rejoiced, and presented to him handkerchiefs dipped in the blood of Somerset, for whom they thought he suffered rather late than undeserved punishment. So certain it is (saith the historian), that the debts both of cruelty and mercy go never unpaid.
