“Penta” in Greek is 5, as in pentagon or Pentecost which is 50. Moses came down from Mt. Sinai with the tablets and instructions which are the first 5 books of our Old Testament. The Hebrew word Torah stands for Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. From Passover to Pentecost, there are 7 weeks plus one day. Pentecost is sometimes called the festival of Weeks: the Hebrew word is Shavuot. On the same day that Jews (and the disciples) were celebrating Moses giving these instructions, the Holy Spirit, our comforter, arrived!
