The Lord of Hosts, the Lamb
Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight and the rough places plain:
Revelation 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; 13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. 14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. 15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; 16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: 17 For the great day of his wrath is come; and who shall be able to stand?
Some of the scriptural reasoning that the Lord of Host is the lamb (rocks, dens, caves, shaking of the earth). The day of the Lord accompanies lowering of the proud.
Isaiah 2:10 10Enter into the rock, and hide thee in the dust, for fear of the LORD, and for the glory of his majesty. 11The lofty looks of man shall be humbled, and the haughtiness of men shall be bowed down, and the LORD alone shall be exalted in that day. 12For the day of the LORD of hosts shall be upon every one that is proud and lofty, and upon every one that is
lifted up; and he shall be brought low: 13And upon all the cedars of Lebanon, that are high and lifted up, and upon all the oaks of Bashan, 14And upon all the high mountains, and upon all the hills that are lifted up, 15And upon every high tower, and upon every fenced wall, 16And upon all the ships of Tarshish, and upon all pleasant pictures. 17And the loftiness of man shall be bowed down, and the haughtiness of men shall be made low: and the LORD alone shall be exalted in that day.
18And the idols he shall utterly abolish. 19And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth. 20In that day a man shall cast his idols of silver, and his idols of gold, which they made each one for himself to worship, to the moles and to the bats; 21To go into the clefts of the rocks, and into the tops of the ragged rocks, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth. 22Cease ye from man, whose breath is in his nostrils: for wherein is he to be accounted of?
The Reign of the Lord hosts
Isaiah 24 16From the uttermost part of the earth have we heard songs, even glory to the righteous. But I said, My leanness, my leanness, woe unto me! the treacherous dealers have dealt treacherously; yea, the treacherous dealers have dealt very treacherously. 17Fear, and the pit, and the snare, are upon thee, O inhabitant of the earth. 18And it shall come to pass, that he who fleeth from the noise of the fear shall fall into the pit; and he that cometh up out of the midst of the pit shall be taken in the snare: for the windows from on high are open, and the foundations of the earth do shake. 19The earth is utterly broken down, the earth is clean dissolved, the earth is moved exceedingly. 20The earth shall reel to and fro like a drunkard, and shall be removed like a cottage; and the transgression thereof shall be heavy upon it; and it shall fall, and not rise again. 21And it shall come to pass in that day, that the LORD shall punish the host of the high ones that are on high, and the kings of the earth upon the earth. 22And they shall be gathered together, as prisoners are gathered in the pit, and shall be shut up in the prison, and after many days shall they be visited. 23Then the moon shall be confounded, and the sun ashamed, when the LORD of hosts shall reign in mount Zion, and in Jerusalem, and before his ancients gloriously.
Both Great and small and rich and poor
Isaiah 24 1Behold, the LORD maketh the earth empty, and maketh it waste, and turneth it upside down, and scattereth abroad the inhabitants thereof. 2And it shall be, as with the people, so with the priest; as with the servant, so with his master; as with the maid, so with her mistress; as with the buyer, so with the seller; as with the lender, so with the borrower; as with the taker of usury, so with the giver of usury to him.
3The land shall be utterly emptied, and utterly spoiled: for the LORD hath spoken this word. 4The earth mourneth and fadeth away, the world languisheth and fadeth away, the haughty people of the earth do languish. 5The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant.
