This may be off topic but if you want to be creeped out, read this. I found it very disturbing.
To me,this points out that the sacrificial system of the Temple believed in a literal thirst for blood. It is the priest that says "I thirst" but it is probably a corruption of an older right where God says he thirsts, and is given blood. Think about it. The person who made this post was making a connection between the Passover ritual and the death of Christ. But Jesus said this before he died and he did not take the offering. It sounds like Jesus was reciting a line from an invocation of God.
( I can not post links yet so I copied part of this)
At satanic rituals, where they sacrifice animals and even babies sometimes, the priest would say...i thirst.
If the priest had to thirst, and jesus said
he was thirsty on the cross (not for blood obviously), then it means that jesus was the
high priest and not the little lamb on the chopping block.
Anyway...the reason jesus said he was thirsty is all together a different one.
The isrealites use to 'put' their sins on a ram, and send the ram off into the desert and abandon it there. It is here where the ram would suffer from thirst.
This is why jesus, like the ram abandoned, said, 'father father why have you forsaken me', and he said....'i thirst'.
