'Addition' in the Bible

I am certain that whatever God does will be for ever. No addition may be made to it, nothing may be taken from it; and God has done it so that man may be in fear before him.

This is an evil in all that is done under the sun: there is one fate for everyone. In addition, the hearts of people are full of evil, and madness is in their hearts while they live—after that they go to the dead.

In addition, no human being knows his time: Like fish captured in a cruel net, or as birds caught in a snare, so also are human beings caught by bad timing that surprises them.

In addition to the Teacher being a wise man, he constantly taught the people knowledge; he weighed, explored, and arranged many proverbs.

Be warned, my son, of anything in addition to them. There is no end to the making of many books, and much study is exhausting to the body.
