Adam Clarke on 1 Samuel 28:13

I saw gods ascending out of the earth - The word אלהום elohim, which we translate gods, is the word which is used for the Supreme Being throughout the Bible; but all the versions, the Chaldee excepted, translate it in the plural number, as we do. The Chaldee has, I see מלאכא דיי malacha dayeya, an angel of the Lord, ascending from the earth. This sight alarmed the woman; it was what she did not expect; in this she could not recognise her familiar, and she was terrified at the appearance.
