'Holy' in the Bible

The governor told them that they should not eat of the most holy things [the priests’ food] until a priest stood up with Urim and Thummim [who by consulting these articles in his breastplate could determine God’s will in the matter].

Then I said to them, “You are holy to the Lord, the utensils are holy, and the silver and the gold are a freewill offering to the Lord God of your fathers.

For they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has intermingled with the peoples of the lands. Indeed, the officials and chief men have been foremost in this unfaithful act and direct violation [of God’s will].”

But now for a brief moment grace has been [shown to us] from the Lord our God, who has left us a surviving remnant and has given us a peg (secure hold) in His holy place, that our God may enlighten our eyes and give us a little reviving in our bondage.
