Woe to you who desire the day of the Lord! Why would you want the day of the Lord? It is darkness and not light; It is as if a man fled from a lion and a bear met him, or went into the house and leaned with his hand against the wall and a serpent bit him. Shall not the day of the Lord be darkness, not light? Even very dark with no brightness in it? I hate, I despise your feasts, and I will not smell a savor or take delight in your solemn assemblies. Though you offer Me your burnt offerings and your cereal offerings, I will not accept them, neither will I look upon the peace or thank offerings of your fatted beasts. Take away from Me the noise of your songs, for I will not listen to the melody of your harps. But let justice run down like waters and righteousness as a mighty and ever-flowing stream.
Amos 5:18-24 AMP

Thus He showed me, and behold, the Lord stood upon a wall with a plumb line, with a plumb line in His hand. [II Kings 21:13; Isa. 34:11.] And the Lord said to me, Amos, what do you see? And I said, A plumb line. Then said the Lord, Behold, I am setting a plumb line as a standard in the midst of My people Israel. I will not pass by and spare them any more [the door of mercy is shut]. And the [idolatrous] high places of Isaac (Israel) shall be desolate and the sanctuaries of Israel shall be laid waste, and I will rise with the sword against the house of King Jeroboam [who set up the golden calf shrines]. Then Amaziah the priest of [the golden calf shrine at] Bethel sent to Jeroboam king of Israel, saying, Amos has conspired against you in the midst of the house of Israel; the land is not able to bear all his words. [I Kings 12:31, 32.] For thus Amos has said, Jeroboam shall die by the sword and Israel shall surely be led away captive out of his land. Also Amaziah said to Amos, O you seer, go! Flee back to the land of Judah [your own country], and eat your bread and live out your profession as a prophet there [as I perform my duties here]. But do not prophesy any more at Bethel, for it is the king’s sanctuary and a seat of his kingdom. [Luke 10:10-12.] Then Amos said to Amaziah, I was no prophet [by profession]! Neither was I a prophet’s son; [but I had my occupation] I was a herdsman and a dresser of sycamore trees and a gatherer of sycamore figs. And the Lord took me as I followed the flock and the Lord said to me, Go, prophesy to My people Israel. Now therefore listen to the word of the Lord: You say, Do not prophesy against Israel and drop no statements not complimentary to the house of Isaac. Therefore thus says the Lord: Your wife shall be a harlot in the city and your sons and your daughters shall fall by the sword, and your land shall be divided up by line; you yourself shall die in an unclean and defiled land, and Israel shall surely go forth out of his land into exile.
