Eliyahu does not execute God's mission to appoint Haza’el and Yehu. The appointments are ultimately executed by Elisha - but with many discrepancies from God’s original command. Transferring the appointments from Eliyahu to Elisha is not the rejection of an unpleasant command; rather, it transforms the mission and softens it through the milder personality of the prophet Elisha.
