Acts 5:21

5:21 When they heard this, they entered the temple courts at daybreak and began teaching.

Now when the high priest and those who were with him arrived, they summoned the Sanhedrin – that is, the whole high council of the Israelites – and sent to the jail to have the apostles brought before them.

Acts 5:23

5:23 “We found the jail locked securely and the guards standing at the doors, but when we opened them, we found no one inside.”
