They replied, "We met a man who told us, "Go back to the king who sent you and ask him, "Is it because there is no God in Israel that you're going to consult with Baal-zebub, the god of Ekron? Therefore you won't be getting up from that bed on which you're lying. You will most certainly die!"'"

Then Elijah spoke to the king, "This is what the LORD says: "Since you sent messengers to consult with Baal-zebub, the god of Ekron is it because there is no God in Israel with whom to consult regarding his word? therefore you're not getting up from the bed on which you're lying. You certainly will die!'"

"This is what the LORD says, "I have certainly observed the blood of Naboth and his sons, and I will repay you on this property," declares the LORD.' "Therefore take the body and throw it in the field, just as the LORD said."

"Don't let Hezekiah deceive you, because he will prove to be unable to deliver you from my control. And don't let Hezekiah make you trust in the LORD by telling you, "The LORD will certainly deliver us and this city will not be handed over to the king of Assyria."
