The figure representing the crucifixion is completely drained. The head is hanging down and turned slightly, and the hands and fingers are pulling down. The legs and feet come to a point, almost like the last droplet of water. We see a connection biblically between the rock that was struck by Moses and brought water and Jesus declaring himself as the water of life, now being poured out to the last as a drink offering.
In the concentration camps, it was easier to die from thirst than from starvation. In this panel the Holocaust figure is crouching with one hand cupped searching for the water and with the other hand almost touching the crucifixion in identification with this word. He understands what thirst is.
