For years, I've been told that the fear of the LORD is only reverential trust, and no more.

So, the following must have been very, very, very reverential:

Jeremiah 5:22 Fear ye not me? saith the LORD: will ye not tremble at my presence, which have placed the sand for the bound of the sea by a perpetual decree, that it cannot pass it: and though the waves thereof toss themselves, yet can they not prevail; though they roar, yet can they not pass over it?
