David captures the infinite-personal God with the first sentence of Psalm 23, “The LORD [infinite] is my shepherd [personal].” In the ancient Near East nothing else came close to this picture of intimacy. Occasionally an ancient king would be described as a shepherd of his people, but the gods were never interested in “little old me.” The words me or my, which sound like “ee” in Hebrew, ring thirteen times through the psalm. The infinite God is interested in me.
