322 X3

322 is the occult/luciferian secret society/club of Yale.

Also refers to the high unholy day of the occult world 3-22, near the Spring Equinox.

Also refers to Genesis 3:22, where G-d mentions that mankind is getting to a point in history where he thinks of himself as gods and that mankind would be able to achieve any evil of desire.

G-d put a sudden stop to that. But mankind has been hard at work to regain that power. G-d will only let it go so far.
