Charles Ellicott Commentary 2 Kings 16:13

"And he burnt his burnt-offering and his meal-offering, and poured his drink-offering, and sprinkled the blood of his peace-offerings, upon the altar." — 2 Kings 16:13 (ASV)

And he burnt his burnt offering... —The verse describes the thank-offering of Ahaz for his recent deliverance from deadly peril. From the present narrative, it appears that he offered it to Jehovah. The account in 2 Chronicles 28:23 must be understood to refer to other sacrifices instituted by Ahaz, who, like most of his contemporaries, thought the traditional worship of Jehovah not incompatible with the forms of worship of foreign deities. (Compare to 2 Kings 16:3–4.)
