“This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the Lord—a lasting ordinance.

And this day shall be unto you for a memorial; and ye shall keep it a feast to the Lord throughout your generations; ye shall keep it a feast by an ordinance for ever.
