That is what the verse says look up strongs and the word is blood
Strong's Greek: 129. αἷμα (haima) -- blood

When the Messiah returns His garments will be stained with blood (and it is not His own).
Isaiah 63
Who
is this that cometh from Edom, with dyed garments from Bozrah? this
that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save…
Why
is Your apparel red,
And Your garments like one who treads in the winepress?
“I have trodden the winepress alone,
And from the peoples no one
was with Me.
For I have trodden them in My anger,
And trampled them in My fury;
Their blood is sprinkled upon My garments,
And I have stained all My robes.
For the day of vengeance
is in My heart,
And the year of My redeemed has come.
I looked, but
there was no one to help,
And I wondered
That
there was no one to uphold;
Therefore My own arm brought salvation for Me;
And My own fury, it sustained Me.
I have trodden down the peoples in My anger,
Made them drunk in My fury,
And brought down their strength to the earth.”
I believe most people (christians) think the Bible is a neat little book with little stories to make movies about.
