Jesus is sending out the disciples in pairs. He is talking with two disciples and has His hand raised as if He is telling them which direction to go. In the background and foreground are other pairs who already have been sent on their way.
1 After this the Lord appointed seventy-two others and sent them on ahead of him, two by two, into every town and place where he himself was about to go.
Mark 6
7 And he called the twelve and began to send them out two by two, and gave them authority over the unclean spirits.
