God is called “LORD of hosts” over 200 times in the Hebrew Scriptures, over 60 times appearing in Isaiah. “Hosts” can be understood as a significant number or an army. The notion of an army seems to be more plausible (cf. 2 Kings 6:15–17) because by the time we arrive at chapters 13–23, where God pronounces judgment, the language is interesting when we follow it. God calls his “holy ones” and “mighty ones” (13:3). God musters these for battle, coming from the end of heaven (13:4). Earlier in chapter 6, we saw an assembling of the heavenly court, God, with the seraphim. There’s one similar passage to Isaiah 6, and that’s 1 Kings 22:19–21. In both of these passages, God is seated on a throne, he asks for a volunteer, the court has a verbal exchange, a volunteer announces himself, and the mission is to deceive God’s people who have angered him with their sinfulness.
A heavenly court is attested to not only in the passages mentioned and in Job 1:6–11; 2:1–6; Zechariah 3:1–5. Isaiah 6:10 seems like a problematic passage when God commissions the prophet to dupe the people essentially. However, when taken with the passage from 1 Kings 22 and Ezekiel 14:4–5, it makes sense that God would answer them according to their heart’s desire (cf. Is. 19:14). Against whom, then, will this heavenly army war? Other hosts of heaven were assigned to oversee the nations, but some became rebellious and received worship as gods (Deut. 32:8 [LXX], 17; Ps. 96:5; Dan. 10). The battle of the faithful and rebellious hosts ensue with the results being mirrored on earth—sometimes the angels fighting against the physical enemy. Divine warfare is a motif in Exodus. Each plague corresponds to YHWH attacking one of Egypt’s gods: e.g., the first plague is directed at Ḥapi, the Nile-god; the second at Ḥeqet, the frog goddess; the fifth at Apis, the bull and Hathor, the cow; the eighth, ninth, and tenth plagues at Ra.
Angels minister to those who are to obtain salvation (Heb. 1:14), so it would stand that they would offer protection of the righteous one (Ps. 91:2, 11–12). A common belief was that earthly rulers mirrored the actions of the divine beings, so when the king of Babylon is spoken against, later believers associated some of the jargon used of him with Satan (Is. 14:12–15). Lucifer, meaning “Day Star,” is plausible as usage for Satan, given other passages about stars and their link with angels (Job. 38:7; Rev. 12:3–4).
By the time we arrive at Ahaz’s death—anywhere between 715–725 BCE—Philistia is urged to not rejoice at the transition of monarchs. Ahaz had agreed to Assyrian domination, but that would change upon the end of his reign and the beginning of Hezekiah’s. Hezekiah changed allegiance to Egypt and led a rebellion against the Assyrian king. Isaiah 14:29 seems to refer to Ahaz as a serpent, and a viper comes from him like a seraph. Hezekiah, we will learn, subdued the Philistines (2 Kings 18:8), and did much good for Judah and Jerusalem as the rest of Isaiah’s oracle points out (14:30–32; cf. 2 Kings 18:6–7).
The remaining oracles are poems of promised judgment against evildoer nations. God judges Babylon, Assyria, Philistia, Moab, Syria and Israel, Ethiopia, Egypt, and Jerusalem. Yet, God gives a couple of rays of hope. First, he will have mercy on Jacob and settle Israel in their land (14:1–2). Second, God will set one on David’s throne to judge with justice (16:5). Judgment sounds harsh, but God will give grace too.
