Do you see how Ahab humbles himself before me?

God knows that Elijah can literally see Ahab, but he wants Elijah to understand that Ahab's sorrow is genuine. Alternate translation: "I have seen how Ahab humbles himself before me." or "Look at how Ahab humbles himself before me." (See: rc://en/ta/man/jit/figs-rquestion)

in his days ... in his son's day

"during his lifetime ... during his son's lifetime"
