Surely the Lord Yahweh will do nothing, Unless he reveals his secret to his servants the prophets.
God then will do nothing without revealing first his secret to the Prophets. He calls it a secret, because men are perplexed when God executes vengeance on them, and stand amazed: but when they are in time warned, then what God designs becomes evident to them, and they know the cause and the source of punishment. Thus then the secret is revealed which was hid from miserable men: and the guilt of the people is doubled, when, after these threatening, they do not repent.
