Offer a sacrifice of thanksgiving of that which is leavened, And proclaim free will offerings and brag about them: For this pleases you, you children of Israel," says the Lord Yahweh.
The special meat offering of the thank offering was to be without leaven Leviticus 7:12. To “offer a sacrifice of thanksgiving with leaven” was a direct infringement of God’s appointment. It proceeded from the same frame of mind, as the breach of the greatest. Self-will was their only rule. What they willed, they kept; and what they willed, they brake. Amos bids them then go on, as they did in their willfulness, breaking God’s commands of set purpose, and keeping them by accident.
