'Deluding' in the Bible

For if there is any one who thinks himself to be somebody when he is nobody, he is deluding himself.

For this reason God will send upon them a deluding influence so that they will believe what is false,

But the [Holy] Spirit explicitly and unmistakably declares that in later times some will turn away from the faith, paying attention instead to deceitful and seductive spirits and doctrines of demons,

But be ye doers of the word, and not hearers only, deluding your own selves.
