My soul thirsteth for God, for the living God,.... Who is so called, in opposition to the idols of the Gentiles, which were lifeless statues; and who is the author, giver, and maintainer of natural life; and who has promised and provided eternal life in his Son; and is himself the fountain of life, and the fountain of living waters, and a place of broad rivers and streams: particularly his lovingkindness, which is better than life, is a pure river of water of life, the streams where make glad the saints; and hence it is that the psalmist thirsted after God, and the discoveries of his love: saying, when shall I come and appear before God? meaning, not in heaven, as desiring the beatific vision; but in the tabernacle, where were the worship of God, and the ark, the symbol of the divine Presence, and where the Israelites appeared before him, even in Zion; see Psa 84:7.
