'Holy' in the Bible

Therefore I want the men in every place to pray, lifting up holy hands, without anger and disputing or quarreling or doubt [in their mind].

And great, we confess, is the mystery [the hidden truth] of godliness:He (Jesus Christ) who was revealed in human flesh,Was justified and vindicated in the Spirit,Seen by angels,Preached among the nations,Believed on in the world,Taken up in glory.

But the [Holy] Spirit explicitly and unmistakably declares that in later times some will turn away from the faith, paying attention instead to deceitful and seductive spirits and doctrines of demons,

Do not neglect the spiritual gift within you, [that special endowment] which was intentionally bestowed on you [by the Holy Spirit] through prophetic utterance when the elders laid their hands on you [at your ordination].
