Deuteronomy 16:5-9

BBE(i) 5 The Passover offering is not to be put to death in any of the towns which the Lord your God gives you: 6 But in the place marked out by the Lord your God as the resting-place of his name, there you are to put the Passover to death in the evening, at sundown, at that time of the year when you came out of Egypt. 7 It is to be cooked and taken as food in the place marked out by the Lord: and in the morning you are to go back to your tents. 8 For six days let your food be unleavened bread; and on the seventh day there is to be a holy meeting to the Lord your God; no work is to be done. 9 Let seven weeks be numbered from the first day when the grain is cut.
