'Holy' in the Bible

Let there be no sound before the Lord God: for the day of the Lord is near: for the Lord has made ready an offering, he has made his guests holy.

Her prophets are good-for-nothing persons, full of deceit: her priests have made the holy place unclean and have gone violently against the law.

In that day you will have no shame on account of all the things in which you did evil against me: for then I will take away from among you those who were lifted up in pride, and you will no longer be lifted up with pride in my holy mountain.

The Lord your God is among you, as a strong saviour: he will be glad over you with joy, he will make his love new again, he will make a song of joy over you as in the time of a holy feast.
