In the Old Testament, ♥♥♥♥♥ is a common noun, as a fallen creation of God, as a rebellious subject of the power of God, who, against his own will, can ultimately contribute to the fulfillment of God's plan[9]. In the Bible, this word refers to people[10][11]. The exception is probably the book of Chronicles[12][13].

With regard to the angel, the very first mention in the Bible appears in the book of Numbers[14], where the word is used in the direct meaning of “hindering”[15].

As the name of a certain angel, ♥♥♥♥♥ first appears in the book of Zechariah[16], where ♥♥♥♥♥ is the accuser at the heavenly court.

According to Christian tradition, ♥♥♥♥♥ first appears on the pages of the Bible in the book of Genesis in the form of a serpent, who seduced Eve with the temptation to eat the forbidden fruit from the Tree of the Knowledge of Good and Evil, as a result of which Eve and Adam sinned with pride and were expelled from paradise, and doomed to earn their bread in sweat of the face with hard work[17]. As part of God's punishment for this, all ordinary snakes are forced to "walk on their belly" and feed on "the dust of the ground"[18].

The Bible also describes ♥♥♥♥♥ as Leviathan[19]. Here he is a huge sea creature or a flying dragon[20][21].

In a number of books of the Old Testament, ♥♥♥♥♥ is called an angel who tests the faith of the righteous[22]. In the book of Job, ♥♥♥♥♥ questions Job's righteousness and invites the Lord to test him. ♥♥♥♥♥ is clearly subordinate to God and is one of his servants (bnei Ha-Elohim - "sons of God", in the ancient Greek version - angels)[23] and cannot act without his permission. He can lead the peoples and bring down fire on the Earth[24], as well as influence atmospheric phenomena[25], send diseases[26].

In the Christian tradition, Isaiah's prophecy about the king of Babylon is attributed to ♥♥♥♥♥[27]. He was created as an angel, but having become proud and desiring to be equal to God[28], he was cast down to earth, becoming after the fall the "prince of darkness", the father of lies, a murderer[29] - the leader of a rebellion against God. From the prophecy of Isaiah[30] the "angelic" name of ♥♥♥♥♥ is taken - הילל, translated as "luminiferous" (lat. Lucifer)[31]. Many theologians (despite the fact that the word of the Lord for Ezekiel was addressed to the king of Tyre[32]) refer to ♥♥♥♥♥ also a passage from the Book of the Prophet Ezekiel[33]:
