Acts 4:3

And they laid hands on them, and put them in hold unto the morrow: for it was now eventide.

As Walker said. "This jailing of the apostles was illegal; no charge was placed against them; it was a highhanded abuse of authority."[6] In the light of this, we should not make too much of the fact that, contrary to the night trial of Jesus, which was also illegal, they did, on this occasion, defer the trial until daytime on the morrow. This was not due to any concern for holy law, but they simply needed time to figure out what they would do.

The unhappiness of the Sadducees over the fact of Jesus' resurrection and the successful proclamation of the gospel was commented upon thus, by Scott:

Miserable is their case to whom the glory of Christ's kingdom is a grief; for, since the glory of that kingdom is everlasting, it follows of course that their grief shall be everlasting also.[7]
