'Hallow' in the Bible

With his finger he shall sprinkle some of the blood on the altar of burnt offering seven times and cleanse it and consecrate it from the uncleanness of the Israelites.

And you shall consecrate the fiftieth year and proclaim freedom [for the slaves] throughout the land to all its inhabitants. It shall be a Jubilee (year of remission) for you, and each of you shall return to his own [ancestral] property [that was sold to another because of poverty], and each of you shall return to his family [from whom he was separated by bondage].

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.

Sanctify My Sabbaths and keep them holy; and they shall be a sign between Me and you, that you may know [without any doubt] that I am the Lord your God.’
