ציטירנדיקער פּירוש אויף יונה 1:6

This is the answer to these questions. People transgress due to four causes: slovenliness, heresy, desire, taking liberties,⁷⁵The Hebrew expression here is “love of freedom.” I believe the point of the cause of sin is that the person is of the opinion that he can do whatever he wants. as it says: “They say, ‘by our tongues we shall travail; with lips such as ours who shall be our master?” (Ps. 12:5) God causes adversity because of these spiritual illnesses in order to cause them to turn in repentance so that they can be saved.
• Slovenliness: A person who sinks into a deep slumber causing him to forget the Lord. For such a person the travail is to face the dangers of the sea, as the sailors said to Jonah: “How can you be sleeping so soundlessly? Get up and call to your God!” (Jonah 1:6)
• Heresy: Someone who leaves the path of truth, as Solomon said in his parable: “Let your mind not wander down her⁷⁶The passage is speaking of the person who goes in search of wanton women. Ettlinger interprets this as a reference to heresy. ways; do not stray unto her paths.” (Prov. 7:25) The travails for such a person is to wander in the wilderness, off the king’s path, so that he is far from his path and is both spiritually hungry and thirsty.
• Desire: Of this person the Psalmist says “All food was loathsome to them; they reached the gates of death.” Their punishment is that they are unable to enjoy any of the simple pleasures because of illness.
• Taking liberties: The punishment for such a person is that he is imprisoned in a jail, a place of darkness.

"He shall return to his earth" - For the bones are, in their structure, of earth, and they are the foundations of the body. The meaning of the word "עשתונותיו" is "his thoughts", like [it says in Yonah 1:6]: "Perhaps God will think (יתעשת) [of us and we will not be lost]." [this being] like saying "God will think, will think of me."

A most “Jewish” Rebuke
Moreover, the language employed by the captain is decidedly “Jewish”. After pushing Yonah to call out to his God, the captain says perhaps “HaElokim”, “the God” (Yonah 1:6) will listen to our prayers. The captain, who began the Pasuk with pagan assumptions that Yonah’s God is one among many, suddenly shifts into a monotheistic mode, invoking “the” (i.e. singular) God. Perhaps the captain is tailoring his words to his audience - Yonah. But the captain began by appealing to Yonah to call out to Elokecha, your God. Moreover, if the captain was aware of Yonah’s religious position why does he inquire into Yonah’s religion once Yonah arrives on deck?
