'Untrue' in the Bible

But his concubine was unfaithful to him, and left him and went to her father’s house in Bethlehem of Judah, and stayed there for a period of four months.

If I had said, “I will say this,” [and expressed my feelings],I would have betrayed the generation of Your children.

Your [drunken] eyes will see strange thingsAnd your mind will utter perverse things [untrue things, twisted things].
