'Sanctify' in the Bible

Consecrate a fast,Proclaim a solemn assembly,Gather the eldersAnd all the inhabitants of the landTo the house of the Lord your God,And cry out to the Lord [in penitent pleadings].

Gather the people, sanctify the congregation,Assemble the elders,Gather the children and the nursing infants.Let the bridegroom come out of his roomAnd the bride out of her bridal chamber. [No one is excused from the assembly.]
