When they saw him, they bowed down to him, but some doubted.

When he saw Jesus from afar, he ran and bowed down to him,

Becoming terrified, they bowed their faces down to the earth. They said to them, "Why do you seek the living among the dead?

When Jesus therefore had received the vinegar, he said, "It is finished." He bowed his head, and gave up his spirit.
