Charles Ellicott Commentary Isaiah 63:2

"Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winevat?" — Isaiah 63:2 (ASV)

Wherefore art thou red ... ?—The wondering question shows that the colour is not that of the warrior’s usual dress. The Hebrew word for “red” (âdom) connects itself with Edom , as batsir (“vintage”) probably with Bozrah.
