What’s with the four tassels?
Deuteronomy 21 has this seemingly random list of laws and regs. Some involve personal conduct, like what to do with disobedient sons, or when someone commits adultery. Others seem more like building codes, such as, build a railing around your roof to keep people from falling. Stuck in the middle of this list is the instruction to make sure you wear a tassel on the four corners of the hem of your outer garment. These tassels were to be a reminder of the commandments of God.
I was reading the blog of a Messianic Jew recently, who said that each tassel was to have blue thread, wrapped in accordance with the name of YHWH. So, the “Y” or Hebrew Yod would have the number of wraps corresponding to its number in the order of the Hebrew alphabet, and so on for each following letter.
Is it possible that the woman who touched the hem of Jesus’ garment, actually touched one of these tassels?
