'Know the Truth' in the Bible

till I gat me to one of them that stood by, to know the truth, concerning all these things. So he told me, and made me understand the interpretation of these things.

After this, I required diligently to know the truth concerning the fourth beast, which was so far unlike the other beasts, and so horrible: whose teeth were of iron, and his nails of brass: which devoured and destroyed, and stamped the residue under his feet.

I desired also to know the truth, as touching the ten horns that he had upon his head, and this other which came up afterward, before whose face there fell down three: which horn had eyes and a mouth that spake presumptuous things, and looked with a grimmer visage than his fellows.
