Matthew Poole and continuators on Jonah 1:12

12 And he said unto them , Take me up , and cast me forth into the sea , so shall the sea be calm unto you , for I know that for my sake this great tempest is upon you .

He readily gives them advice for their safety.

This he spake as a Prophet directed of God, and not as some Iewish Rabbi thinks choosing to die rather than to go to Nineveh.

Throw me overboard into the Sea, no other way must you deal with me than this, and this way I not only direct as expedient, but from God I give you it as a Command, and you must do it, thus my God-will punish my disobedience and contempt.

As a Prophet I assure you the Tempest shall cease, and you be safe, and by that you may know I being in the ship, endanger'd you all.

I am assured of this, and though I have been your danger, and this was my fault, yet it shall not be my fault if you be drowned.

For my sin which God will punish, but not by my own act, I must not leap over board, 'tis a crime God will punish by that Justice which is in this place,

and will be till you have executed God's sentence on me, which I willingly submit to.
