This passage is often misinterpreted literally as divine approval or instruction for using leavened bread in thank offerings or publicizing freewill contributions, overlooking the prophetic sarcasm that condemns Israel's superficial, self-pleasing religiosity as transgression rather than genuine devotion, or as unrelated to the surrounding context of God's failed attempts to provoke repentance through calamities.
Amos 4:5
King James Version (1769)
5 And offer a sacrifice of thanksgiving with leaven, and proclaim and publish the free offerings: for this liketh you, O ye children of Israel, saith the Lord God.
Amos 4:5 employs biting sarcasm from God to expose Israel's hypocritical worship, urging them mockingly to continue offering leavened thank offerings and proclaiming freewill gifts as they delight in such empty rituals, which violate true obedience and reveal their unrepentant hearts amid divine judgments meant to turn them back to Him.
