Charles Ellicott Commentary Exodus 16:7

"and in the morning, then ye shall see the glory of Jehovah; for that he heareth your murmurings against Jehovah: and what are we, that ye murmur against us?" — Exodus 16:7 (ASV)

And in the morning, then you will see the glory of the Lord. —The reference here is to the manna, which in the morning lay round about the host (Exodus 16:13), not to the appearance of Exodus 16:10, which preceded the coming of the quails, and was not—as far as we are told—in the morning. The glory of God was strikingly revealed in a gift which was not transient, but secured permanently the subsistence of the people so long as it might be necessary for them to continue in the wilderness. (Compare the parallelism of Exodus 16:8; Exodus 16:12.)
