Matthew Henry Commentary 1 Kings 21:1-4

"And it came to pass after these things, that Naboth the Jezreelite had a vineyard, which was in Jezreel, hard by the palace of Ahab king of Samaria. And Ahab spake unto Naboth, saying, Give me thy vineyard, that I may have it for a garden of herbs, because it is near unto my house; and I will give thee for it a better vineyard than it: or, if it seem good to thee, I will give thee the worth of it in money. And Naboth said to Ahab, Jehovah forbid it me, that I should give the inheritance of my fathers unto thee. And Ahab came into his house heavy and displeased because of the word which Naboth the Jezreelite had spoken to him; for he had said, I will not give thee the inheritance of my fathers. And he laid him down upon his bed, and turned away his face, and would eat no bread." — 1 Kings 21:1-4 (ASV)

Naboth, perhaps, had been pleased that he had a vineyard situated so near the palace, but the situation proved fatal to him. Many people's possessions have been their snare, and their proximity to greatness has often had bad consequences.

Discontent is a sin that is its own punishment and causes people to torment themselves. It is a sin that is its own parent; it does not arise from one's condition, but from the mind. For example, we find Paul contented in a prison, while Ahab was discontented in a palace.

Ahab had all the delights of Canaan, that pleasant land, at his command: the wealth of a kingdom, the pleasures of a court, and the honors and powers of a throne. Yet all this availed him nothing without Naboth's vineyard.

Wrong desires expose people to continual vexations, and those who are disposed to fret, however well-off they may be, can always find something to fret about.
