What did Elisha tell the king to do with the captured soldiers?

Answer: Feed them and send them home

Elisha said to set food and water before them; the king prepared a great feast and sent them back to their master.

““Do not kill them,” he replied. “Would you kill those you have captured with your own sword or bow? Set food and water before them, that they may eat and drink and then return to their master.””— 2 Kings 6:22 (BSB)
