With only twenty-two symbols, it could be taught, in a relatively short time, to everyone. We see evidence of this at many places in Tanakh, the Hebrew Bible. Isaiah says "All your children shall be taught of the Lord and great shall be the peace of your children" (Isaiah 54:13), implying universal education."
