'Truth' in the Bible

Then shalt thou inquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought among you;

When it is reported to you or you hear of it, then investigate it thoroughly. When the truth has been established that this detestable thing has been done in Israel,

And if this thing hath been truth -- tokens of virginity have not been found for the damsel --

He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.
