Isaiah 63:2

Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winefat?

Cross-reference

Isaiah 63:1 introduces the warrior with stained garments, prompting the question in verse 2 about their redness.

Isaiah 63:6 answers the question: the red garments come from trampling nations in anger like a winepress.
