Jon 1:3
Jonah sets out upon his journey; not to Nineveh, however, but to flee to Tarshish, i.e., Tartessus, a Phoenician port in Spain (see at Gen 10:4 and Isa 23:1), “from the face of Jehovah,” i.e., away from the presence of the Lord, out of the land of Israel, where Jehovah dwelt in the temple, and manifested His presence (cf. Gen 4:16); not to hide himself from the omnipresent God, but to withdraw from the service of Jehovah, the God-King of Israel.
The motive for this flight was not fear of the difficulty of carrying out the command of God, but, as Jonah himself says in Jon 4:2, anxiety lest the compassion of God should spare the sinful city in the event of its repenting. He had no wish to co-operate in this; and that not merely because “he knew, by inspiration of the Holy Spirit, that the repentance of the Gentiles would be the ruin of the Jews, and, as a lover of his country, was actuated not so much by envy of the salvation of Nineveh, as by unwillingness that his own people should perish,” as Jerome supposes, but also because he really grudged salvation to the Gentiles, and feared lest their conversion to the living God should infringe upon the privileges of Israel above the Gentile world, and put an end to its election as the nation of God.
He therefore betook himself to Yāphō, i.e., Joppa, the port on the Mediterranean Sea (vid., comm. on Jos 19:46), and there found a ship which was going to Tarshish; and having paid the sekhârâh, the hire of the ship, i.e., the fare for the passage, embarked “to go with them (i.e., the sailors)to Tarshish.”
