Passover: Observed at the Place Designated by God
Source: Nav
Deuteronomy 16:5–7
You are not to sacrifice the Passover animal in any of the towns that the LORD your God is giving you. / You must only offer the Passover sacrifice at the place the LORD your God will choose as a dwelling for His Name. Do this in the evening as the sun sets, at the same time you departed from Egypt. / And you shall roast it and eat it in the place the LORD your God will choose, and in the morning you shall return to your tents.
