In the daytime he led them with a cloud, and all the night with a fiery light.

In the daytime also he led them with a cloud. He did it all. He alone. He brought them into the wilderness, and he led them through it; it is not the Lord's manner to begin a work, and then cease from it while it is incomplete. The cloud both led and shadowed the tribes.

In these verses, I. The psalmist observes the late rebukes of Providence that the people of Israel had been under, which they had brought upon themselves by their dealing treacherously with God, Psa 78:9-11.
