Matching Quote

"And Ahab said to Naboth, "Give me your vineyard, so that I may have it for a vegetable garden, because it is near my house; I will give you a better vineyard for it; or, if it seems good to you, I will give you its value in money." But Naboth said to Ahab, "The LORD forbid that I should give you my ancestral inheritance." Ahab went home resentful and sullen because of what Naboth the Jezreelite had said to him; for he had said, "I will not give you my ancestral inheritance." He lay down on his bed, turned away his face, and would not eat."
