John Wesley on 2 Kings 2:12

My father - So he calls him for his fatherly affection to him, and for his fatherly authority which he had over him, in which respect the scholars of the prophets are called their sons. He saw his own condition like that of a fatherless child, and laments it accordingly. The chariot, &c. - Who by thy example, and counsels, and prayers, and power with God, didst more for the defence and preservation of Israel than all their chariots and horses. The expression alludes to the form of chariots and horses which he had seen.
