This is the oblation of Aaron and of his sons, which they shall offer unto Jehovah in the day when he is anointed: the tenth part of an ephah of fine flour for a meal-offering perpetually, half of it in the morning, and half thereof in the evening.
but he shall acknowledge the first-born, the son of the hated, by giving him a double portion of all that he hath; for he is the beginning of his strength; the right of the first-born is his.
