John Gill Commentary 2 Kings 22:15

"And she said unto them, Thus saith Jehovah, the God of Israel: Tell ye the man that sent you unto me," — 2 Kings 22:15 (ASV)

And she said to them
The king's messengers:

thus says the Lord God of Israel ;
being immediately inspired by him, she spoke in his name, as prophets did:

tell the man that sent you to me ;
which may seem somewhat rude and unmannerly to say of a king; but when it is considered she spoke not of herself, but representing the King of kings and Lord of lords, it will be seen and judged of in another light.
