He reveals His secret to His servants the prophets-Amos 1-3.

The words of Amos, who was among the sheepbreeders of Tekoa, which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash, king of Israel, two years before the earthquake. Thus says the Lord: “For three transgressions of Judah, and for four, I will not turn away its punishment, Because they have despised the law of the Lord , And have not kept His commandments. Their lies lead them astray, Lies which their fathers followed. Thus says the Lord: “For three transgressions of Israel, and for four, I will not turn away its punishment, Because they sell the righteous for silver, And the poor for a pair of sandals. They pant after the dust of the earth which is on the head of the poor, And pervert the way of the humble. A man and his father go in to the same girl, To defile My holy name. They lie down by every altar on clothes taken in pledge, And drink the wine of the condemned in the house of their god. Hear this word that the Lord has spoken against you, O children of Israel, against the whole family which I brought up from the land of Egypt, saying: “You only have I known of all the families of the earth; Therefore I will punish you for all your iniquities.” Surely the Lord God does nothing, Unless He reveals His secret to His servants the prophets. For they do not know to do right,’ Says the Lord, ‘Who store up violence and robbery in their palaces.’” Hear and testify against the house of Jacob,” Says the Lord God, the God of hosts, “That in the day I punish Israel for their transgressions, I will also visit destruction on the altars of Bethel; And the horns of the altar shall be cut off And fall to the ground.
