Gevurot 16:24-26

Orthodox Jewish Bible

²⁴ And the soher, having received such an order, threw them into the inner beis hasohar, and he fastened their feet in the stock. [IYOV 13:27; 33:11; YIRMEYAH 20:2,3; 29:26]

²⁵ And about chatzot halailah Rav Sha’ul and Sila were davening and were singing niggunim to Hashem, and the prisoners were listening to them.

²⁶ And, suddenly, there came a gevaltike earthquake, so that the beis hasohar was shaken to its foundations, and immediately were opened all delatot (doors) and all sharsherot (chains) were unfastened.
