John Gill's Bible Commentary Ver. 3. Then take the box of oil, and pour it on his head , etc.] When in the chamber together alone: and say, thus saith the Lord, I have anointed thee king over Israel ; which was done, not with the anointing oil in the temple, which could not be come by; and with which, as Kimchi from their Rabbins says, only the kings of the house of David were anointed, and they only when there was a division, or the crown was translated to another family, as was the case now; but with common oil, or the oil of balsam, such as the prophet had in his house: then open the door and flee, and tarry not ; lest he should be examined by the captains, and come into danger; though before he went out he was to say what is recorded in ( 2 Kings 9:7-10).
Matthew Henry Commentary
Verses 1-10 - In these and the like events, we must acknowledge the secret working of God, disposing men to fulfil his purposes respecting them. Jehu wa anointed king over Israel, by the Lord's special choice. The Lord stil had a remnant of his people, and would yet preserve his worship amon them. Of this Jehu was reminded. He was commanded to destroy the hous of Ahab, and, as far as he acted in obedience to God, and upon righ principles, he needed not to regard reproach or opposition. The murde of God's prophets is strongly noticed. Jezebel persisted in idolatr and enmity to Jehovah and his servants, and her iniquity was now full.
