Charles H. Spurgeon on Psalms 92:12

The song now contrasts the condition of the righteous with that of the graceless. The wicked "spring as the grass", but The righteous shall flourish like a palm tree, whose growth may not be so rapid, but whose endurance for centuries is in fine contrast with the transitory verdure of the meadow. When we see a noble palm standing erect, sending all its strength upward in one bold column, and growing amid the dearth and drought of the desert, we have a fine picture of the godly man, who in his uprightness aims alone at the glory of God; and, independent of outward circumstances, is made by divine grace to live and thrive where all things else perish. The text tells us not only what the righteous is, but what he shall be; come what may, the good man shall flourish, and flourish after the noblest manner. He shall grow like a cedar in Lebanon. This is another noble and long lived tree. "As the days of a tree are the days of my people", saith the Lord. On the summit of the mountain, unsheltered from the blast, the cedar waves its mighty branches in perpetual verdure, and so the truly godly man under all adversities retains the joy of his soul, and continues to make progress in the divine life. Grass, which makes hay for oxen, is a good enough emblem of the unregenerate; but cedars, which build the temple of the Lord, are none too excellent to set forth the heirs of heaven.
