12:4 I will open mine eyes - I will watch over my people for good. This eye of God open upon his people, is his wise, powerful, gracious providence for them. With blindness - All their warriors in their consults shall have as little of foresight, as a blind man hath of sight.
12:1-8 Here is a Divine prediction, which will be a heavy burden to all the enemies of the church. But it is for Israel; for their comfort and benefit. It is promised that God will make foolish the counsels, and weaken the courage of the enemies of the church. The exact meaning is not clear; but God often begins by calling the poor and despised; and in that day even the feeblest will resemble David, and be as eminent in courage and every thing good. Desirable indeed is it that the examples and labours of Christians should render them as fire among wood, as a torch in a sheaf, to kindle the flame of Divine love, to spread religion on the right hand and on the left.
