The annual Passover celebration date given in Numbers is based on a calendar determined by the waxing and waning of the moon, as opposed to our calendar, which is founded upon earth’s revolution around the sun. That is why Passover and therefore Easter fall on different dates in our calendar every year. We celebrate Easter in proximity to Passover because Jesus took a Passover meal on the night He was betrayed by Judas. Passover’s importance to Jewish history and Christian history is impossible to summarize here. I will note that in Numbers 9:14 foreigners are commanded to take the Passover in the same way as Israelites. This is noteworthy because it clearly indicates that God intends for the nations to join Israel’s descendants in the worship of Yahweh (YHWH moving forward). We as readers need to understand early in our Bible reading journey that God’s intention to bring the nations to knowledge of YHWH doesn’t begin with Jesus’ kingdom proclamation. God’s expects Israel to be the means to bring the good news of God’s salvation, represented well by the Passover meal, and provide hope for all who wish to worship the true God. In fact, if you are ever invited to a Jewish Passover Seder, I recommend taking that opportunity, for it is expected in the Jewish Bible that foreigners would be welcome in this practice. God has always desired to bring the nations under His wing, even while bringing His goodness to the world through a chosen people. May our celebration of our Passover (Lord’s Supper) also extend to the nations like God intends!
