Charles Ellicott Commentary Acts 7:39

"to whom our fathers would not be obedient, but thrust him from them, and turned back in their hearts unto Egypt," — Acts 7:39 (ASV)

To whom our fathers would not obey.—The historical parallelism is continued. The people rejected Moses then (the same word is used as in Acts 7:27) as they were rejecting Christ now, even after He had shown Himself to be their redeemer from a worse than Egyptian bondage.

In their hearts turned back again into Egypt.—The sin was one often repeated, but the history referred to is probably that in Exodus 16:3. For a later example see Numbers 11:5.
