Adam Clarke Bible Commentary

Took every man his garment - This was a ceremony by which they acknowledged him as king; and it was by such a ceremony that the multitudes acknowledged Jesus Christ for the Messiah and King of Israel, a little before his passion: see Mat 21:7 (note), and the note there. The ceremony was expressive: "As we put our garments under his feet, so we place every thing under his authority, and acknowledge ourselves his servants." On the top of the stairs - The Chaldee, the rabbins, and several interpreters, understand this of the public sun-dial; which in those ancient times, was formed of steps like stairs, each step serving to indicate, by its shadow, one hour, or such division of time as was commonly used in that country. This dial was, no doubt, in the most public place; and upon the top of it, or on the platform on the top, would be a very proper place to set Jehu, while they blew their trumpets, and proclaimed him king. The Hebrew מעלות maaloth is the same word which is used Kg2 20:9-11, to signify the dial of Ahaz; and this was probably the very same dial on which that miracle was afterwards wrought: and this dial, מעלות maaloth, from עלה alah, to go up, ascend, was most evidently made of steps; the shadows projected on which, by a gnomon, at the different elevations of the sun, would serve to show the popular divisions of time. See the notes on Kg2 20:9 (note), etc.
