'Denied' in the Bible

Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

Then the king of Israel called all the elders of the land, and said, Mark, I pray you, and see how this man seeketh mischief: for he sent unto me for my wives, and for my children, and for my silver, and for my gold; and I denied him not.

This also were an iniquity to be punished by the judge: for I should have denied the God that is above.
