Jehovah, he says, in the midst of thee strong, will save. He repeats what he had said, but more fully expresses what might have appeared obscure on account of its brevity. He therefore shows here more at large the benefit of God’s presence—that God will not dwell idly in his Church, but will be accompanied with his power. For what end? To save. We hence see that the word גבור, gebur, ascribed to God, is very emphatical; as though he had said, that God would not be idle while residing in the midst of his Church, but would become its evident strength. And it is worthy of notice, that God exhibits not himself as strong that he may terrify his elect, but only that he may become their preserver.
