Charles Spurgeon Commentary Acts 4:23

"And being let go, they came to their own company, and reported all that the chief priests and the elders had said unto them." — Acts 4:23 (ASV)

You can always tell a man by his company. Had these people been ungodly, they would have done as the ungodly do when they come out of prison: they would have gone off to their old drinking companions. But they are believers, and they go to their own company.
