The Bible usually uses the name of God in the singular (e.g. Ex. 20:7 or Ps. 8:1), generally using the terms in a very general sense rather than referring to any special designation of God. However, general references to the name of God may branch to other special forms which express his multifaceted attributes. The Old Testament reveals YHWH (often vocalized with vowels as "Yahweh" or "Jehovah") as the personal name of God, along with certain titles including El Elyon and El Shaddai. Jah or Yah is an abbreviation of Jahweh/Yahweh, and often sees usage by Christians in the interjection "Hallelujah", meaning "Praise Jah", which is used to give God glory. In the New Testament the terms Theos, Kyrios and Patēr (πατήρ i.e. Father in Greek) are additionally used to reference God.
