Thematic Bible: Treading the, of the sufferings of Christ

Why is Your apparel red, And Your garments like the one who treads in the wine press? "I have trodden the wine trough alone, And from the peoples there was no man with Me I also trod them in My anger And trampled them in My wrath; And their lifeblood is sprinkled on My garments, And I stained all My raiment.
