'Single' in the Bible

For what happens to people also happens to animals a single event happens to them: just as someone dies, so does the other. In fact, they all breathe the same way, so that a human being has no superiority over an animal. All of this is pointless.

For there is not a single righteous man on earth who practices good and does not sin.

Everyone shares the same experience: a single event affects the righteous, the wicked, the good, the clean, the unclean, whoever sacrifices, and whoever does not sacrifice. As it is with the good person, so also it is with the sinner; as it is with someone who takes an oath, so also it is with someone who fears taking an oath.

Wisdom is better than weapons of war, and a single sinner can destroy a lot of good.
