Charles H. Spurgeon on Psalms 65:8

Thou makest the outgoings of the morning and evening to rejoice. That is, thou makest men to rejoice, they are glad, they rejoice in, or at, the outgoings in the morning. And at the evening men rejoice too, for then they go to their rest, being wearied with the labour of the day. Or, we may thus expound it: Thou makest men who live at the outgoings of the morning, and at the outgoings of the evening, to rejoice. As if it had been said, Thou makest the eastern people and the western people, all people from east to west, rejoice. And that which makes all people to rejoice, naturally, is the rising of light with them in the east, and the coming of light towards them in the west. Joseph Caryl.
