2 Kings 9:5

And when he came, behold, the captains of the host were sitting; and he said, I have an errand to thee, O captain. And Jehu said, Unto which of all us? And he said, To thee, O captain.

He said, I have an errand to thee, O captain, х hasaar (H8269), prince, leader; Septuagint, ho (G3588) archoon (G758)]. The words used here, both in the Hebrew text and in the Septuagint, are different from what is rendered "captain," 2 Kings 9:25. The act of anointing being done through a commissioned prophet was a divine intimation of his investiture with the sovereign power; but it was sometimes done long prior to the actual possession of the throne (1 Samuel 16:13); and in like manner the commission had in this instance been given also a long time before to Elijah, who, for good reasons, left it in charge to Elisha, and he waited God's time and command for executing it.
