'Deny' in the Bible

Next some of the Sadducees came forward (who deny that there is a Resurrection)

You do not know Him, but I know Him perfectly; and were I to deny my knowledge of Him, I should resemble you, and be a liar. On the contrary I do know Him, and I obey His commands.

"What are we to do with these men?" they asked one another; for the fact that a remarkable miracle has been performed by them is well known to every one in Jerusalem, and we cannot deny it.

unless you can deny that it is one and the same God who will pronounce the circumcised to be acquitted on the ground of faith, and the uncircumcised to be acquitted through the same faith.

If we deny that we have sinned, we make Him a liar, and His Message has no place in our hearts.

Satan's throne is there; and yet you are true to Me, and did not deny your faith in Me, even in the days of Antipas My witness and faithful friend, who was put to death among you, in the place where Satan dwells.
