It is amazing, and especially how he weaves diverse Scripture into the explanation. I wish we could ask him to explain more so we could trace the chain back to its traditional origin. The washing of hands is done today by observant Jews.
Ahh, but the washing of the hands is Talmud, not Torah, and directly disputed by Yeshua:
Mat 15:1 Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying,
Mat 15:2 Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread.
Mat 15:3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?
(e-Sword:KJV)
HOW they transgressed the commandment of YHWH is that 'washing the hands' was not a commandment of YHWH... Do not add to, nor take away from...
