Ahab killed many sheep and cattle for him and the people

This means that he had these animals slaughtered to prepare a feast for the people. Also, Ahab himself would not have prepared the animals, but rather would have commanded his workers to do it. Alternate translation: "Ahab commanded his workers to slaughter many sheep and cattle for a feast for Jehoshaphat and the people" (See: rc://en/ta/man/jit/figs-explicit and rc://en/ta/man/jit/figs-metonymy)
