Like The Revelation, Leviticus is built around sevens.
Every seventh day a Sabbath.
Every seventh year a sabbatical year.
Pentecost is seven weeks after Passover.
In seventh month were feasts of Shofars, Yom Kippur, and Tabernacles.
Pentecost lasts seven days.
Passover lasts seven days.
Does Leviticus have insight into The Revelation?
