I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread.
I have been young ... righteous forsaken - i:e., forsaken utterly (cf. Psalms 37:28). He comprises all ages in the ideal character that speaks as a father would address his children.
Nor his seed begging bread - i:e., continuously. Temporarily David had in his destitution begged sustenance from the rich Nabal. The very object of the psalm is to counteract the temptation to fretfulness at the temporary wants of the godly. But, alike in the Old and the New Testaments, the godly are exempt from permanent abandonment as to the needs even of this life. He who commands us to pray, Give us this day our daily bread, will not mock His children by withholding that which He Himself has encouraged them to ask, with the implied promise that He will grant it. He does not raise hopes only to disappoint them. They who make heaven their end will not be allowed to want any necessary on the way (Matthew 6:33; Psalms 84:11; Romans 8:28; Romans 8:32).
