I don’t go beyond what is recorded in Scripture. I could say I ‘assume,’ Moses wore tassels but that would be a worthless statement. I have no firsthand knowledge and the Scripture doesn’t speak directly to the point.
The term, ‘tradition,’ is not used to characterize the direct commands of God. Tassels are a command, not a tradition.
Here is Jesus directly addressing the issue of tradition [Mark 7]
12 you no longer permit him to do anything for his father or his mother;
13 thus invalidating the word of God by your tradition which you have handed down; and you do many things such as that.”
That’s great, because it’s a specific commandment, not a tradition. Do Not murder. Put fringes on the corners...
Don’t cook...
Don’t covet...
Honor mom and dad...
Take branches (of beautiful trees....)
