'Execution' in the Bible

The witnesses must be first to begin the execution, and then all the people are to join in afterward. In this way you will purge evil from among you.

Obadiah said, "What sin have I committed that you are ready to hand your servant over to Ahab for execution?

So Jehosheba, the daughter of King Joram and sister of Ahaziah, took Ahaziah's son Joash and sneaked him away from the rest of the royal descendants who were to be executed. She hid him and his nurse in the room where the bed covers were stored. So he was hidden from Athaliah and escaped execution.
