Charles H. Spurgeon on Psalms 92:2

In the morning. When indeed the mind after the rest of the night is more active, devoted and constant. In other parts of the day, as at noon, or in the afternoon, many sounds of business disturb, and greater lassitude oppresses. Compare Ps 5:4 59:17 58:2 88:14 Ps 119:147-148, where this same part of the day is celebrated as the fittest for sacred meditations. However, this ought not to be taken exclusively, as if, in the morning alone, and not also at noon or in the evening, it was suitable to celebrate divine grace. —Martin Geier.
