This Q was just asked a few days ago, so here is what I posted then as it still applies:
Names for the Jewish/Christian God found in the bible run parallel with the names of gods in the Canaanite pantheon, found in the Ugarat, the ones found in the bible are as follows: El, Elyon: Supreme God, Creator El- Shaddai: Lord or God of the mountain El-Roi El-Olam YHWH, Yahweh, or Jehovah
The name El in Hebrew eventually became just a title so to speak meaning god Elyon or Elohim was translated as a Plural or an Ultimate (many say because he is the almighty).

Many Bible have removed God's name from the Bible and have exchanged it for Lord or other titles, this occurred when a superstitious idea arose among the Jews that it was wrong even to pronounce God's name. The time when the superstition occurred is not documented but is assumed to have occurred after the Babylonian exile in 607-537 B.C.E.
However, in the Hebrew Scriptures the New World Translation contains the divine name 6,973 times, because the translators took into account the fact that in some places the scribes had replaced the divine name. Plus in the Christian Greek Scriptures it appears 237 times.
God himself wants us to call him by his name, as he himself said so in Isaiah 42:8: "I am Jehovah. That is my name; and to no one else shall I give my own glory, neither my praise to graven images."
