Acts 15:16 - Matthew Poole's English Annotations on the Holy Bible

After this; in the days of the Messiah. I will return: the word may be taken in both voices. If actively, it signifies God's returning uuto the Gentiles, from whom he had departed. If passively, it foreshows their returning unto God, whom they had forsaken. The tabernacle; the house, expressed by a tabernacle, (as frequently in Scripture), because that anciently they dwelt only in tabernacles; and here for the throne of David, who was a type of Christ, whose kingdom is over all. God does promise less than he does perform, for he did not only restore the tabernacle of David, in Christ, but raised it to a far greater splendour and glory in its spiritual state. And though St. James here does not exactly keep unto the words of the prophet, he speaks their sense and meaning.
