'Killing' in the Bible

Then he called out to the Lord, "O Lord, my God, are you also bringing disaster on this widow I am staying with by killing her son?"

When Jezebel was killing the Lord's prophets, Obadiah took one hundred prophets and hid them in two caves in two groups of fifty. He also brought them food and water.)

Certainly my master is aware of what I did when Jezebel was killing the Lord's prophets. I hid one hundred of the Lord's prophets in two caves in two groups of fifty and I brought them food and water.
