John Gill Commentary 2 Kings 1:16

"And he said unto him, Thus saith Jehovah, Forasmuch as thou hast sent messengers to inquire of Baal-zebub, the god of Ekron, is it because there is no God in Israel to inquire of his word? therefore thou shalt not come down from the bed whither thou art gone up, but shalt surely die." — 2 Kings 1:16 (ASV)

And he said to him Elijah to King Ahaziah when introduced into his chamber; and after some discourse passed between them, he confirmed what he had said to his messengers, and expressed it in the same language as in (2 Kings 1:3 2 Kings 1:4) (See Gill on 2 Kings 1:3) (See Gill on 2 Kings 1:4)
