Adam Clarke on Jonah 4:5

So Jonah went out of the city - I believe this refers to what had already passed; and I therefore agree with Bp. Newcome, who translates, "Now Jonah Had gone out of the city, and Had sat," etc.; for there are many instances where verbs in the preterite form have this force, the ו vau here turning the future into the preterite. And the passage is here to be understood thus: When he had delivered his message he left the city, and went and made himself a tent, or got under some shelter on the east side of the city, and there he was determined to remain till he should see what would become of the city. But when the forty days had expired, and he saw no evidence of the Divine wrath, he became angry, and expostulated with God as above. The fifth verse should be read in a parenthesis, or be considered as beginning the chapter.
