This first picture is of Leor and Brent standing in front of the Western Wall.
In this picture Itamar is preparing to lay tefillin. This is related to Deuteronomy. 6 where the sons of Israel are told to bind the Word of God on the arms and foreheads.
It's bound on the left arm because it's closest to the heart. In Rabbinic tradition this is called the mark of God.
This is me watching from behind the dividing wall. I'm the one on the right.
In this photo Itamar is reading from the Torah.
