'Preserve' in the Bible

The customer will no longer pay the seller while both parties are alive, for the vision against their whole crowd will not be revoked. Each person, for his iniquity, will fail to preserve his life.

and say 'This is what the sovereign Lord says: Woe to those who sew bands on all their wrists and make headbands for heads of every size to entrap people's lives! Will you entrap my people's lives, yet preserve your own lives?

This is because you have disheartened the righteous person with lies (although I have not grieved him), and because you have encouraged the wicked person not to turn from his evil conduct and preserve his life.

When a wicked person turns from the wickedness he has committed and does what is just and right, he will preserve his life.
