Albert Barnes Commentary 2 Kings 16:15

"And king Ahaz commanded Urijah the priest, saying, Upon the great altar burn the morning burnt-offering, and the evening meal-offering, and the king`s burnt-offering, and his meal-offering, with the burnt-offering of all the people of the land, and their meal-offering, and their drink-offerings; and sprinkle upon it all the blood of the burnt-offering, and all the blood of the sacrifice: but the brazen altar shall be for me to inquire by." — 2 Kings 16:15 (ASV)

The bronze altar shall be for me to inquire by—most modern commentators translate this as: “As for the bronze altar, it will be for me to inquire (or consider) what I shall do with it.”
