49 He let loose on them his fierce anger,
wrath, indignation, and distress,
a company of destroying angels.
50 He made a path for his anger;
he did not spare them from death,
but gave their lives over to the plague.
51 He struck all the firstborn in Egypt,
the first issue of their strength in the tents of Ham.
Might be referring to Numbers 16:41-50 (below)
These might refer to the same being?
15 So the Lord sent a pestilence on Israel from that morning until the appointed time; and seventy thousand of the people died, from Dan to Beer-sheba. 16 But when the angel stretched out his hand toward Jerusalem to destroy it, the Lord relented concerning the evil, and said to the angel who was bringing destruction among the people, “It is enough; now stay your hand.” The angel of the Lord was then by the threshing floor of Araunah the Jebusite. 17 When David saw the angel who was destroying the people, he said to the Lord, “I alone have sinned, and I alone have done wickedly; but these sheep, what have they done? Let your hand, I pray, be against me and against my father’s house.”
Sennacherib’s Defeat and Death
(Isa 37:36–38; 2 Chr 32:20–23)
35 That very night the angel of the Lord set out and struck down one hundred eighty-five thousand in the camp of the Assyrians; when morning dawned, they were all dead bodies. 36 Then King Sennacherib of Assyria left, went home, and lived at Nineveh.
41 On the next day, however, the whole congregation of the Israelites rebelled against Moses and against Aaron, saying, “You have killed the people of the Lord.” 42 And when the congregation had assembled against them, Moses and Aaron turned toward the tent of meeting; the cloud had covered it and the glory of the Lord appeared. 43 Then Moses and Aaron came to the front of the tent of meeting, 44 and the Lord spoke to Moses, saying, 45 “Get away from this congregation, so that I may consume them in a moment.” And they fell on their faces. 46 Moses said to Aaron, “Take your censer, put fire on it from the altar and lay incense on it, and carry it quickly to the congregation and make atonement for them. For wrath has gone out from the Lord; the plague has begun.” 47 So Aaron took it as Moses had ordered, and ran into the middle of the assembly, where the plague had already begun among the people. He put on the incense, and made atonement for the people. 48 He stood between the dead and the living; and the plague was stopped. 49 Those who died by the plague were fourteen thousand seven hundred, besides those who died in the affair of Korah. 50 When the plague was stopped, Aaron returned to Moses at the entrance of the tent of meeting.
What is the connection between Yahweh and the destroyer?
11 The Lord said to Moses, “I will bring one more plague upon Pharaoh and upon Egypt; afterwards he will let you go from here; indeed, when he lets you go, he will drive you away. 2 Tell the people that every man is to ask his neighbor and every woman is to ask her neighbor for objects of silver and gold.” 3 The Lord gave the people favor in the sight of the Egyptians. Moreover, Moses himself was a man of great importance in the land of Egypt, in the sight of Pharaoh’s officials and in the sight of the people.
4 Moses said, “Thus says the Lord: About midnight I will go out through Egypt. 5 Every firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the female slave who is behind the handmill, and all the firstborn of the livestock. 6 Then there will be a loud cry throughout the whole land of Egypt, such as has never been or will ever be again.
12 For I will pass through the land of Egypt that night, and I will strike down every firstborn in the land of Egypt, both human beings and animals; on all the gods of Egypt I will execute judgments: I am the Lord. 13 The blood shall be a sign for you on the houses where you live: when I see the blood, I will pass over you, and no plague shall destroy you when I strike the land of Egypt.
23 For the Lord will pass through to strike down the Egyptians; when he sees the blood on the lintel and on the two doorposts, the Lord will pass over that door and will not allow the destroyer to enter your houses to strike you down. 24 You shall observe this rite as a perpetual ordinance for you and your children. 25 When you come to the land that the Lord will give you, as he has promised, you shall keep this observance. 26 And when your children ask you, ‘What do you mean by this observance?’ 27 you shall say, ‘It is the passover sacrifice to the Lord, for he passed over the houses of the Israelites in Egypt, when he struck down the Egyptians but spared our houses.’ ” And the people bowed down and worshiped.
28 The Israelites went and did just as the Lord had commanded Moses and Aaron.
The Tenth Plague: Death of the Firstborn
29 At midnight the Lord struck down all the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the prisoner who was in the dungeon, and all the firstborn of the livestock.
14 When in the future your child asks you, ‘What does this mean?’ you shall answer, ‘By strength of hand the Lord brought us out of Egypt, from the house of slavery. 15 When Pharaoh stubbornly refused to let us go, the Lord killed all the firstborn in the land of Egypt, from human firstborn to the firstborn of animals. Therefore I sacrifice to the Lord every male that first opens the womb, but every firstborn of my sons I redeem.’
