I'm no jew (no really!!!) but one anon's post about 4 10 20 got me to thinking about the psalms and how some of them have mnemonics on top of the verses. Would the name zach have significance? The letters as I found them in the hebrew alphabet make( זאק ( 4-10-20 R->L spell what appears to be the name Zach as translated from hebrew. Just a thought. Or maybe I'm way off :)
