Albert Barnes Commentary 1 Samuel 2:27

"And there came a man of God unto Eli, and said unto him, Thus saith Jehovah, Did I reveal myself unto the house of thy father, when they were in Egypt [in bondage] to Pharaoh`s house?" — 1 Samuel 2:27 (ASV)

A man of God - See the note on Judges 13:6. The sudden appearance of the only prophet mentioned since Deborah—without a name or any notice of his country—is remarkable.
