There's a documentary called "Awake Zion" that attempts to connect the beliefs of Rastas and Jews. I thought I watched it on Netflix but it doesn't appear to be available at this time. It was very interesting if you can find it.
From the Wiki page for the documentary:
Although Jews and Rastas appear different, both claim figures from the Old Testament as their forefathers, both send a message of truth and love to their followers, both speak of Zion, both have integrated their beliefs into their lifestyles and Rastafarians also claim to be descended from the children of Israel. Haim, who relates to and enjoys both cultures, raises the question, "if we're both identifying with the same things, are we not then identifying with one another?"
