'Saint' in the Bible

They envied Moses also in the camp, and Aaron the saint of the LORD.

Then I heard one saint speaking, and another saint said unto that certain saint which spake, How long shall be the vision concerning the daily sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?

Salute every saint in Christ Jesus. The brethren which are with me greet you.
