'Loud' in the Bible

For uttering arrogant words of vanity [pompous words disguised to sound scholarly or profound, but meaning nothing and containing no spiritual truth], they beguile and lure using lustful desires, by sensuality, those who barely escape from the ones who live in error.

But the Day of the Lord will come like a thief; on that day the heavens will pass away with a loud noise, the elements will burn and be dissolved, and the earth and the works on it will be disclosed.
