Acts 16:23-25

King James Version

²³ And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely:

²⁴ Who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks.

²⁵ And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
