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.
Jewish Publication Society of America Version (JPS1917) - Deuteronomy 16:6 >but at the place which the LORD thy God shall choose to cause His name to dwell in, there thou shalt sacrifice the passover-offering at even, at the going down of the sun, at the season that thou camest forth out of Egypt.
