מַדּ֥וּעַ אָדֹ֖ם לִלְבוּשֶׁ֑ךָ וּבְגָדֶ֖יךָ כְּדֹרֵ֥ךְ בְּגַֽת׃
「你的衣服為甚麼是紅的？你的衣裳為甚麼像在酒榨中踹葡萄的人？」
Ibn Ezra
ללבושך Thine apparel.8A. V., In thine apparel. Comp. c. xxxii., Note 1. The preposition ל is pleonastic as in 1) לאבשלום Chr. 3:2). Like him that treadeth in the winefat. Blood is in colour similar to wine.
Tze'enah Ure'enah
“Why are your robes red” [63:2]. Why are your garments red? He compares the nations to a winepress where one tramples the grapes. So will the Holy One squeeze the nations and trample them.
