"I have been young, and now am old, yet I have not seen the righteous forsaken, nor his children begging for bread" (37:25). Doesn't Scripture tell of righteous people in need?

It does, and Psalm 37 doesn't say that trouble never comes. The verse gives what the psalmist says he has seen over his own life: "I have been young, and now am old, yet I have not seen the righteous forsaken, nor his children begging for bread" (37:25). The same psalm speaks of hard times for the righteous, and each time it says what the LORD does: "They shall not be disappointed in the time of evil. In the days of famine they shall be satisfied" (37:19); "Though he stumble, he shall not fall, for the LORD holds him up with his hand" (37:24); "The wicked watch the righteous, and seek to kill him. The LORD will not leave him in his hand" (37:32-33); and "He is their stronghold in the time of trouble" (37:39). Other Scripture sets down what others saw. The Preacher: "there is a righteous man who perishes in his righteousness, and there is a wicked man who lives long in his evildoing" (Ecclesiastes 7:15). Job, whom the book calls "blameless and upright" (Job 1:1), asks, "Why do the wicked live, become old, yes, and grow mighty in power?" (Job 21:7), and the chapter on Job 21 sets his question beside Psalm 37:1-2. Another psalmist says, "I was envious of the arrogant, when I saw the prosperity of the wicked" (Psalm 73:3). Hebrews, speaking of people it says were "commended for their faith" (Hebrews 11:39), tells of some who went about "being destitute, afflicted, ill-treated" (Hebrews 11:37). Paul writes of his own "hunger and thirst" (2 Corinthians 11:27). These notes set those verses beside Psalm 37:25 and don't say how they fit together.
