The whole of this verse is in the pictorial present in the Hebrew —
“He findeth him in a desert land,
In a waste howling wilderness;
He compasseth him about, He instructeth him,
He guardeth him as the apple of his eye.”
He found him. — This beautiful expression is common to the Old and New Testaments as a description of God’s first revelation of Himself to man. In the case of Hagar it is written (Genesis 16:7), “the angel of Jehovah found her by a fountain of water in the wilderness.” Concerning Jacob, that “He found him in Bethel,” when Jacob said “Surely the Lord is in this place, and I knew it not” (Hosea 12:4; Genesis 28:16). A series of similar passages is closed by the three examples of the lost sheep, the lost money, and the son that had been lost, and was found (Luke 15).
He led him about. — The commoner meaning is given in the margin. Rashi has this remark: “He caused them to abide round about His glory (Shechinah), the tent of the congregation in the middle, and four standards on the four sides.”
