This can be stated in active form. Alternate translation: "whom Jezebel commanded her servants to murder" or "whose deaths were commanded by Jezebel" (See: [[rc://en/ta/man/jit/figs-activepassive]])
This means that Jezebel commanded the people to be killed. Alternate translation: "by an order from Jezebel" or "by Jezebel's command" (See: [[rc://en/ta/man/jit/figs-metonymy]])
