Isaiah 63:1

Amplified Bible

63 Who is this who comes from Edom,
With crimson-stained garments from Bozrah [in Edom],
This One (the Messiah) who is majestic in His apparel,
Marching in the greatness of His might?
“It is I, [the One] who speaks in righteousness [proclaiming vindication], mighty to save.”
