Isaiah 63:1-4

Who is this who comes from Edom, from the city of Bozrah, with his clothing stained red? Who is this in royal robes, marching in his great strength? “It is I, the LORD, announcing your salvation! It is I, the LORD, who has the power to save!” Why are your clothes so red, as if you have been treading out grapes? “I have been treading the winepress alone; no one was there to help me. In my anger I have trampled my enemies as if they were grapes. In my fury I have trampled my foes. Their blood has stained my clothes. For the time has come for me to avenge my people, to ransom them from their oppressors.
