'Purify' in the Bible

Whenever a round of banqueting was over, Job would send for his children and purify them, rising early in the morning to offer burnt offerings for all of them. For Job thought: Perhaps my children have sinned, having cursed God in their hearts. This was Job’s regular practice.

“Nothing of his dwells in his tent;Brimstone (burning sulfur) is scattered over his dwelling [to purify it].

When he raiseth up himself, the mighty are afraid: by reason of breakings they purify themselves.
