When he raiseth up himself; showing himself upon the top of the waters. Or, because of his height, or greatness, or majesty; for he is represented as a king, Job 41:31. The mighty; even the stout-hearted mariners or passengers, who use to be above fear. By reason of breakings; either,
1. Of the sea, caused by his motion, which dasheth the waves in pieces one against another. Or rather,
2. Of their mind and state; by reason of their great danger and distress; which is expressed by this very word, Psalms 60:2 Jonah 2:4. They purify themselves; either,
1. Naturally; that being, the usual effect of great terror. See Ezekiel 7:17. Or rather,
2. Morally, as this word is generally used. Those mariners who ordinarily live in a gross and general neglect of God, and of religion, are so affrighted with this imminent danger, that they cry unto God in their trouble, as is said in like case, Psalms 107:28, and endeavour to purge their consciences from the guilt of their sins, by confessing and seemingly forsaking of them, and to make their peace with God, and obtain his favour and help, by their vows, and promises, and prayers.
