Jonah 1:8

After the lot fell on Jonah, they doubted not but that he was the guilty person, any more than if he had been a hundred times proved to be so: for why did they cast lots, except that they were persuaded that all doubt could thus be removed, and that what was hid could thus be brought to the light? As then this persuasion was fixed in their minds, that the truth was elicited, and was in a manner drawn out of darkness by the lot, they now inquire of Jonah what he had done: for they took this as allowed, that they had to endure the tempest on his account, and also, that he, by some detestable crime, had merited such a vengeance at Gods hand. We hence see that they cast lots, because they fully believed that they could not otherwise find out the crime on account of which they suffered, and also, that lots were directed by the hidden purpose of God: for how could a certain judgment be found by lot, except God directed it according to his own purpose, and overruled what seemed to be especially fortuitous? These principles then were held as certain in a manner by men who were heathens, — that God can draw out the truth, and bring it to the light, — and also, that he presides over lots, however fortuitous they may be thought to be.

This was the reason why they now asked what Jonah had done. Tell us, then, why has this evil happened to us, what is thy work? etc. By work here I do not mean what is wrong, but a kind of life, or, as they say, a manner of living. They then asked how Jonah had hitherto employed himself, and what sort of life he followed. For it afterwards follows, Tell us, whence comest thou, what is thy country, and from what people art thou? They made inquiries, no doubt, on each particular in due order; but Jonah here briefly records the questions.
