44Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. 45And because I tell you the truth, ye believe me not. 46Which of you convinceth me of sin? And if I say the truth, why do ye not believe me? 47He that is of God heareth God's words: ye therefore hear them not, because ye are not of God…

You know the saying speak of the devil and he will appear. It's a common idiom used when someone you were just talking about unexpectedly shows up. The phrase is said to have originated in England during the Middle Ages birthed from a superstition about mentioning the devil. It was initially expressed as "Talk of the Devil," and the belief was that speaking of the devil could cause him to appear, often with negative consequences.

In the Bible, according to various sources, the devil is said to have been spoken of 36 times in the New Testament and spoken of by the name satan 18 times in the old and 35 times in the new with his first appearance being recorded in Genesis when he is referred to as the deceptive and cunning creature, known as the serpent, that tempts Eve to disobey God. Later, the serpent is identified as Satan in Revelation 12:9 and Revelation 20:2.
