Bible Notes Online - Jonah 4 - ESV
Commentary

v1: Although the people of Nineveh repent, avoiding judgment, there are still lessons for Jonah to learn. We see that he does not rejoice, even though others are blessed.

v2: Jonah tries to justify his own disobedience, even claiming God's character justifies his attitude. His statement about God's character is, of course, wonderfully true; yet Jonah's message (3.4) refers only to judgment without escape. 'Why should God be merciful to Gentiles?'

v3: Jonah's self-pity, that God take away his life.

v4: The Lord is patient towards Jonah; Prov 15.1; 2 Tim 2.24-25.

v5-8: The lesson of the vine. Jonah is sulkily waiting to see if God would destroy Nineveh. With the plant, Jonah sees it as a blessing from God; he is more pleased with the giver than the gift; he loves the plant more than the people of Nineveh.

Do we trust in changeable circumstances, or in the unchanging God? Deut 8.2 teaches that the Lord sends our circumstances to reveal the attitudes of our hearts.

v9-10: Jonah is angry about the vine; picturing, or contrasting with, the Lord's concern over Nineveh.

v11: People who cannot discern; perhaps children (Deut 1.39), or is the Lord simply describing the whole population of the city?

We note that Jonah gives the Lord the last word; he has no more answers. Perhaps he has learned his lessons. The conclusion is like Job's words (Job 42.1-6) as he reflects on God's revelation of Himself. "Therefore I despise myself and repent in dust and ashes."
