Exodus 12:23 - Ellicott's Commentary On The Whole Bible

Bible Comments

The destroyer. — The “plague” of Exodus 12:13 is here called “the destroyer” (τὸν ὀλεθρεύοντα, LXX.), as again in Hebrews 12:28. Jehovah seems to have employed an angel, or “angels” (Ps. 79:48) as His agents to effect the actual slaying of the firstborn. (Comp. 2 Samuel 24:16; 1 Chronicles 21:15; 2 Kings 19:35.) There is no struggle or opposition (as Bishop Lowth and Redslob think) between Jehovah and” the destroyer,” who is simply His minister (Hebrews 1:14), bidden to enter some houses and to “pass over” others.

Exodus 12:23

23 For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the LORD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.
