11 The fourteenth day of the second month at even they shall keep it, and eat it with unleavened bread and bitter herbs.
The Passover was to be celebrated in the FIRST month, but Yahweh provided a second time to celebrate it for anyone who was unclean through touching a dead body or on a long journey. All the rules were the same, except it was in the SECOND month.
All who are Christ's are on a journey. We are not yet at home, but are sojourners in this world, waiting to arrive at the New Jerusalem. (Heb 11:13-16) Further, everyone has touched death by sinning (Rom 3:23 & 6:23). But although we have been far from God, and are unclean through our sin, Jesus has brought us near and cleansed us with His blood. So a time is coming when we will celebrate the Passover in the second month.
