'Truth' in the Bible

He said, "Blessed be Yahweh, the God of my master Abraham, who has not forsaken his loving kindness and his truth toward my master. As for me, Yahweh has led me in the way to the house of my master's relatives."

I am not worthy of the least of all the loving kindnesses, and of all the truth, which you have shown to your servant; for with just my staff I passed over this Jordan; and now I have become two companies.

Send one of you, and let him get your brother, and you shall be bound, that your words may be tested, whether there is truth in you, or else by the life of Pharaoh surely you are spies."
