2 Kings 9:3

Then take the box of oil, and pour it on his head
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 ) .
