As per the Law of Moses, you must keep Passover (Pesach) this month if you missed it last month. You should have picked out your lamb two days ago, on Friday April 27. The killing of the lamb happens two days from now, on Tuesday May 1. The ungodly will be celebrating May Day, Beltane, and Walpurgisnacht on this holy day. Do not let that deter you, nor sway you from the course of true worship.
