TSK · Numbers 9:2

Observe the month of Abib, and keep the Passover to Yahweh your God; for in the month of Abib Yahweh your God brought you forth out of Egypt by night.

Josiah kept a Passover to Yahweh in Jerusalem: and they killed the Passover on the fourteenth [day] of the first month.

On the first day of unleavened bread, when they sacrificed the Passover, his disciples asked him, "Where do you want us to go and prepare that you may eat the Passover?"

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.
