'Tempestuous' in the Bible

Our God cometh, and doth not keep silence: A fire devoureth before him, And it is very tempestuous round about him.

Then said they unto him, What shall we do unto thee, that the sea may be calm unto us? for the sea grew more and more tempestuous.

Nevertheless the men rowed hard to get them back to the land; but they could not: for the sea grew more and more tempestuous against them.
