Charles H. Spurgeon on Psalms 65:8

Thou makest the outgoings of the morning and evening to rejoice. How contrary soever light and darkness are to each other, and how inviolable soever the partition between them (Ge 1:4), both are equally welcome to the world in their season; it is hard to say which is more welcome to us, the light of the morning which befriends the business of the day, or the shadows of the evening which befriend the repose of the night. Doth the watchman wait for the morning? so doth the hireling earnestly desire the shadow. Some understand it of the morning and evening sacrifice, which good people greatly rejoiced in, and in which God was constantly honoured. Thou makest them to sing, so the word is; for every morning and every evening songs of praise were sung by the Levites; it was that which the duty of every day required. And we are to look upon our daily worship alone, and with our families, to be both the most needful of our daily business, and the most delightful of our daily comforts; and if therein we keep up our communion with God, the outgoings both of the morning and of the evening are thereby made truly to rejoice. Matthew Henry.
