Also before they burnt the fat, the priest's servant came, and said to the man that sacrificed, Give flesh to roast for the priest; for he will not have sodden flesh of thee, but raw. Before they burnt the fat - They would serve themselves before God was served! This was iniquity and arrogance of the first magnitude.
He will not have sodden flesh - He chooses roast meat, not boiled; and if they had it in the pot before the servant came, he took it out that it might be roasted.
