Some translations set each line of poetry farther to the right than the rest of the text to make it easier to read. The ULB does this with the poetic song in 22:2-51.
David uses many metaphors to express his trust in God's protection: "my rock, my fortress, my shield, the horn of my salvation, my stronghold and my refuge." He used other metaphors to express his hopelessness: "the waves of death surrounded me," "the rushing waters of worthlessness overwhelmed me," "the cords of sheol surrounded me;" "the snares of death trapped me," and "the surging water." He also used metaphors for the victory God gave him: "I can run over a barricade" and "by my God I can leap over a wall."
