Joel 3:16
14 Crowds, great crowds are in the Valley of Decision, for the day of the Lord is near in the Valley of Decision! 15 The sun and moon are darkened; the stars withhold their brightness. 16 The Lord roars from Zion; from Jerusalem his voice bellows out. The heavens and the earth shake. But the Lord is a refuge for his people; he is a stronghold for the citizens of Israel. 17 “You will be convinced that I, the Lord, am your God, dwelling on Zion, my holy mountain. Jerusalem will be holy— conquering armies will no longer pass through it.
1 Enoch 1:5
4 And the eternal God will tread upon the earth, (even) on Mount Sinai, ⌈And appear from His camp⌉ And appear in the strength of His might from the heaven of heavens. 5 And all shall be smitten with fear And the Watchers shall quake, And great fear and trembling shall seize them unto the ends of the earth. 6 And the high mountains shall be shaken, And the high hills shall be made low, And shall melt like wax before the flame 7 And the earth shall be ⌈wholly⌉ rent in sunder, And all that is upon the earth shall perish, And there shall be a judgement upon all (men).
Notes and References
"... Watchers are generally portrayed negatively in Greek BW, but their children are especially decried: in 10:9, they are titled ‘the bastards’, ‘the base ones’, and ‘the sons of fornication’. Part of Michael’s tasking in 10:15 is to “destroy all the spirits of the base ones”. Some ambiguous passages are also present, one of which is 1 Enoch 1:5: “all will be afraid, and the watchers will trust”. These watchers could be understood as obediently accompanying God at Sinai (1 Enoch 1:4, 9; Psalm 68). However, God’s approach shakes the peaks of the earth where the watchers are hidden (1:5). He comes to destroy the impious and their works (1:9). In 1 Enoch 1:5 then, it is unclear if they are rebellious or obedient ... The appearance of the celestial army on the mountain rather than hovering mid-air is likely related to divine council imagery. The mountain of God is the place where the divine assembly meets. There is ANE precedent for spiritual beings on this council also serving as part of the heavenly army. God’s ‘mountain of assembly’ was not restricted to a single geographic location. Moses’ final words in Deuteronomy 33:2 declared: “Yahweh came from Sinai, and he appeared clearly to them from Seir, and he came from mount Paran with the thousands of his holy ones: from his right hand [came] angels for them.” This speech also contains reference to Yahweh’s enthronement as King when in Jeshurun (Deuteronomy 33:5). God is pictured as the Sovereign who can dispatch angelic warriors to accomplish his will (compare Psalm 68). Well-known mountains of God include Eden (Ezekiel 28:13–14), Sinai and Zion (1 Kings 8; Psalm 2:6; Isaiah 2:3; Jeremiah 8:19; Joel 3:16-17; Amos 1:2; Micah 4:7; Zechariah 8:3), but Seir, Horeb, and Paran also became the mount of assembly when the council met ..."
