Numbers 15:20

Eat. Hebrew and Septuagint, "of your dough." They elevated a part towards heaven, and gave it to the priest or Levite, who lived nearest them; and, in case none could be found, as at the present day, they were to burn it in honour of God. Tradition determines the quantity to be between a 40th and a 60th part. (St. Jerome in Ezec. xlv.) This they do every time they bake, according to Philo, and Leo of Modena, (2. 9,) though the law be not clear, and some might think it sufficient to give a part, the first time they baked with new flour.
