'Deny' in the Bible

And Joshua said unto all the people, Behold, this stone shall be a witness unto us, for it hath heard all the words of Jehovah which he spoke unto us; and it shall be a witness against you, lest ye deny your God.

If he destroy him from his place, then it shall deny him: I have not seen thee!

Two things do I ask of thee; deny me them not before I die:

lest I be full and deny thee, and say, Who is Jehovah? or lest I be poor and steal, and outrage the name of my God.
