Psalm 121:5
The LORD is thy keeper: the LORD is thy shade upon thy right hand.
The LORD is thy keeper,.... This explains more fully who it is that keeps Israel and particular believers, and confirms the same; not a creature, but the Lord; the Word of the Lord, as the Targum, in
Ps 121:7: Christ, the Word and Wisdom of God; who is the keeper of his people by the designation of his Father, who has put them into his hands to be kept by him; and by their full will and consent, who commit the keeping of their souls to him; for which he is abundantly qualified, being able as the mighty God; faithful to him that has appointed him; tender and compassionate to those under his care, whom he keeps as the apple of his eye; and diligent and constant, for he keeps them night and day, lest any hurt them: he keeps them as they are his flock, made his care and charge; as they are the vineyard of the Lord of hosts; as they are a city, which, unless the Lord keeps, the watchmen watch in vain; as they are his body and members of it, and as they are his jewels and peculiar treasure: these he keeps in the love of God; in his own hands; in the covenant of grace; in an estate of grace; and in his own ways, safe to his kingdom and glory;
The LORD is thy shade upon thy right hand; he is at the right hand of his people, to hold their right hand; to teach them to go, lead them into communion with himself, and hold them up safe; and to strengthen their right hand, assist them in working, without whom they can do nothing; and to counsel and direct them, and to protect and defend them against all their enemies. So a shadow signifies defence; see Numbers 14:9 Ecclesiastes 7:12; and such great personages are to others; in which sense Virgil {n} uses the word "shadow"; and much more true is this of God himself. And he is like the shadow of a great rock in a weary land; or of a spreading tree, which is a protection from heat, and very reviving and refreshing; see Isaiah 32:2. The allusion may be to the pillar of cloud by day, which guided and guarded the Israelites in the wilderness, and was a shadow from the heat, Isaiah 4:5; as Christ is from the heat of a fiery law, the flaming sword of justice, the wrath of God, and the fiery darts of Satan.
