Arise, go to Nineveh, that great city, and cry against it; for their wickedness is come up before me.
That great city — It is said to have been one hundred and fifty furlongs in length, that is eighteen miles and three quarters, and eleven miles and one quarter in breadth.
 But Jonah rose up to flee unto Tarshish from the presence of the LORD, and went down to Joppa; and he found a ship going to Tarshish: so he paid the fare thereof, and went down into it, to go with them unto Tarshish from the presence of the LORD.
From the presence — From the place where God usually had shewed himself present, by revealing his word and will to his prophets. Perhaps he might think God would not put him upon this work, when he was got into a strange country.
 Then the mariners were afraid, and cried every man unto his god, and cast forth the wares that were in the ship into the sea, to lighten it of them. But Jonah was gone down into the sides of the ship; and he lay, and was fast asleep.
Into the sides — ln some cabin or other, whither he went before the storm arose.
 So the shipmaster came to him, and said unto him, What meanest thou, O sleeper? arise, call upon thy God, if so be that God will think upon us, that we perish not.
Will think upon us — With pity and favour.
 And they said every one to his fellow, Come, and let us cast lots, that we may know for whose cause this evil is upon us. So they cast lots, and the lot fell upon Jonah.
Cast lots — "Lots are an appeal to heaven in doubtful cases, and therefore not to be used but where the matter is undeterminable in any other way."
 Then said they unto him, Tell us, we pray thee, for whose cause this evil is upon us; What is thine occupation? and whence comest thou? what is thy country? and of what people art thou?
Tell us — What hast thou done, for which God is so angry with thee, and with us for thy sake?
 And he said unto them, I am an Hebrew; and I fear the LORD, the God of heaven, which hath made the sea and the dry land.
I fear — I worship and serve the true God; the eternal and almighty God, who made and ruleth the heavens.
 Nevertheless the men rowed hard to bring it to the land; but they could not: for the sea wrought, and was tempestuous against them.
Rowed hard — They were willing to be at any labour to save him.
 Wherefore they cried unto the LORD, and said, We beseech thee, O LORD, we beseech thee, let us not perish for this man's life, and lay not upon us innocent blood: for thou, O LORD, hast done as it pleased thee.
Unto the Lord — Now they all cry to Jonah's God, to Jehovah.
And said — Let us not perish for taking away his life.
Hast done — Sending the tempest, arresting the prophet by it, detecting him by lot, sentencing him by his own mouth, and confirming the condemning sentence by the continuance of the storm.
 Then the men feared the LORD exceedingly, and offered a sacrifice unto the LORD, and made vows.
Feared the Lord — Perhaps as Jonah's casting over-board was a type of Christ's death, so the effect it had upon the mariners might be a type of the conversion of the Heathen from idols unto God.
Made vows — Probably they vowed, they would ever worship him whom Jonah preached, the Creator of heaven and earth.
 Now the LORD had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights.
A great fish — The Hebrew word is, numbered, has appointed him for Jonah's receiver and deliverer. God has the command of all his creatures, and can make any of them serve his designs of mercy to his people.
