Psalms 42:4

That person is compared to a tree planted by streams of water that produces fruit in season and keeps its leaf from withering, and their way prospers. The ungodly are not like that; they are like chaff driven by the wind. The psalm ends by saying the ungodly do not stand in the judgment or remain among the righteous, because the LORD knows the way of the righteous, but the way of the ungodly perishes. Psalm 2: The Anointed King This psalm speaks about nations and rulers stirring up unrest and setting themselves against the LORD and against his Anointed. They speak as if they can break free from God's rule, as though his bonds can be thrown off. The LORD who sits in the heavens responds with scorn and speaks in his wrath. He declares his king set upon Zion, and the Anointed speaks of the decree: he is called the Son and is given the nations for an inheritance. The psalm warns kings and judges to be wise, to serve the LORD with fear, and to rejoice with trembling, ending with a call to honor the Son and a statement that blessed are all who trust in him. Psalm 3: A Psalm of David (Fleeing from Absalom) A Psalm of David, when he flees from Absalom his son. David speaks of many enemies rising up against him and many voices saying there is no help for him in God. He describes pressure on every side and the shame those words bring. David then speaks directly of the LORD as his shield, his glory, and the one who lifts up his head. He says he cries to the LORD and receives an answer from God's holy hill, and he lies down and sleeps because the LORD sustains him. He says he is not afraid though tens of thousands set themselves against him, and he calls on the LORD to arise, asking for deliverance and blessing for God's people.
