Question: "Who is the destroying angel?"
Answer: The destroying angel is also commonly referred to as the angel of death. On numerous occasions, God used angelic beings—heavenly messengers of some kind—to bring judgment to sinners on earth. Various Bible translations refer to this being as a “destroying angel.” There is no clear biblical evidence that any one particular angel was given the title “destroying angel” or “angel of death.” The most we can say is that the Bible’s mentions of a “destroying angel” are references to a heavenly being or beings that came to destroy those under God’s judgment.
The most famous visitation of a destroying angel was on the first Passover. Egypt was about to experience the tenth and final plague, the death of the firstborn. Moses’ instructions to the Hebrews contained this warning: “When the LORD goes through the land to strike down the Egyptians, he will see the blood on the top and sides of the doorframe and will pass over that doorway, and he will not permit the destroyer to enter your houses and strike you down” (Exodus 12:23). Some other translations have “Angel of Death” (GNT) or “death angel” (NLT) instead of “destroyer.” This being is called “the destroyer of the firstborn” in Hebrews 11:28.
Interestingly, the original Hebrew text of Exodus 12:23 does not mention an “angel” at all. It simply says that “the destroyer” or “the spoiler” or “the one who causes damage” would slay the firstborn of Egypt. It could have been the Lord Himself who was the destroyer, although the possibility exists that God sent an angel to do the deed. Psalm 78 recounts the plagues in Egypt and sums them up as God’s unleashing of “a band of destroying angels” (verse 49). The Hebrew word for “angel” is used here, but it is not limited to one particular angel.
A destroying angel—a heavenly messenger who brought destruction—was also sent by God to judge the Israelites because of David’s sin in numbering the people: “The Lord sent a plague on Israel from that morning until the end of the time designated, and seventy thousand of the people from Dan to Beersheba died. When the angel stretched out his hand to destroy Jerusalem, the Lord relented concerning the disaster and said to the angel who was afflicting the people, ‘Enough! Withdraw your hand.’ The angel of the Lord was then at the threshing floor of Araunah the Jebusite. When David saw the angel who was striking down the people, he said to the Lord, ‘I have sinned’” (2 Samuel 24:15–17).
The Assyrians who attacked Jerusalem during King Hezekiah’s reign also met what could be called an angel of death or a destroying angel: “That night the angel of the Lord went out and put to death a hundred and eighty-five thousand in the Assyrian camp. When the people got up the next morning—there were all the dead bodies!” (2 Kings 19:32–35). In this passage and in 2 Samuel 24, the destroying angel is actually called “the angel of the Lord,” which many scholars take to be a reference to Christ in a pre-incarnate appearance.
Another angel who brought death and destruction is mentioned in the judgment of King Herod (Acts 12:23). An angel with lethal intent, identified as “the angel of the Lord,” bearing a sword gives a warning to Balaam (Numbers 22:31–33). And Jesus mentions that angels will be involved in the end-times judgment of the wicked (Matthew 13:49–50). In none of these cases are the angels called “the angel of destruction” or “the angel of death.” We might refer to an angel who metes out God’s judgment as an “angel of destruction,” but it is not an explicitly biblical term.
