'Purify' in the Bible

When the days of their feasting were over, Job would send [for them] and consecrate them, rising early in the morning and offering burnt offerings according to the number of them all; for Job said, “It may be that my sons have sinned and cursed God in their hearts.” Job did this at all [such] times.

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