I. That the city and temple should be rebuilt, v. 18. Jacob's tents, and his dwelling places, felt the effects of the captivity, for they lay in ruins when the inhabitants were carried away captives; but, when they have returned, the habitations shall be repaired, and raised up out of their ruins, and therein God will have mercy upon their dwelling places, that had been monuments of his justice. Then the city of Jerusalem shall be built upon her own heap, her own hill, though now it be no better than a ruinous heap. The situation was unexceptionable, and therefore it shall be rebuilt upon the same spot of ground. He that can make of a city a heap (Isa. xxv. 2) can when he pleases make of a heap a city again. The palace (the temple, God's palace) shall remain after the manner thereof; it shall be built after the old model; and the service of God shall be constantly kept up there and attended as formerly.
