"Take up shield and buckler, and rise up to help me." God said to him, "Do I need a shield?" (Psalms 35:2) "Let them be like chaff before the wind, with the angel of the Lord driving them on." I breathe upon them and they wither. Likewise, Isaiah says (Isaiah 40:6), "A voice says, 'Cry!' And I said, 'What shall I cry?' (Isaiah 40:7) 'All people are grass, their constancy is like the flower of the field.'" God said to him, "David, what are you doing?" He said to him, "I praise You." And so it says, "All my bones shall say, 'Lord, who is like You?'" (Psalms 35:10)
