of the power of the air

Cool contrast in choice of words. This is the reason for the chronological read. 2Chron9 has the Queen of Sheba "breathless". IKing10 has her as having "no more spirit in her". The lesson is clear: that your breath, what sustains your life, is your spirit. And really, what salvation is is letting your sustenance be not your spirit but the spirit of God; walking with Him is allowing that spirit to win out.
