All that the flesh-hook brought up, &c. This was a new custom, which they had profanely introduced. For, not content with the breast and right shoulder, allowed them by God, they took also part of the offerers' share; besides which, they snatched their part before it was heaved and waved, contrary to Leviticus 7:34. Also before they burnt the fat Which entirely belonged to God with the other parts that were to be burned with it. The priest's servant came, &c. This was a high and profane contempt of God, and an additional injury; for they took such parts as they liked best while it was raw, and before that which belonged to God had been offered to him.
