John Gill Commentary Luke 22:57

"But he denied, saying, Woman, I know him not." — Luke 22:57 (ASV)

And he denied him, saying, woman, I know him not .
Startled at the maid's positive assertion, and knowing not how to clear himself any other way, roundly, and at once, denied that Jesus was his master; or that he was a disciple of his; or that he knew any thing of him, or had any acquaintance with him: and thus he that had said he would die with him, rather than deny him, was frightened at a servant maid, and denies him upon the first attack upon him.
