Jeremiah 7:21

The meaning is, Increase your sacrifices as you will. Acid burnt-offering to peace-offerings. All is in vain as long as you neglect the indispensable requirements of obedience and moral purity. Eat flesh is equivalent to sacrifice. The flesh of animals offered in sacrifice was usually eaten by the offerers, and this meal was regarded as a symbol of reconciliation. God and man partook of the same victim, and so were made friends. This passage Jeremiah 7:21 is the Haphtarah (lesson) from the prophets, after the Parashah, Lev. 6–8, or Lesson from the Law. The selection of such a Haphtarah shows that the Jews thoroughly understood that their sacrifices were not the end of the Law, but a means for spiritual instruction.
