Perhaps the oldest name for "god" in the Hebrew Bible, 'E:lohiym אלהים
(God) "Elohim"
is another name used for God. It is a plural form of the older name for God "el".
yhwh יהןה
(Yahweh or LORD) This is the holy name of God; cf. Exodus 3, where Moses learns about this name, although it had been used from the beginning of the text of Genesis. By the time of Jesus, it was no longer pronounced.
adonai אדני
(Lord) This is the ordinary hebrew word which would have referred to a person. The name "Jehovah" was mistakenly derived from combining the vowels of the word "adonai" with the consonants of the tetragrammaton "yhwh". HaShem is used when even saying "adonai" is too holy to speak.
Allāh الله
from ancient times the name for "God" by Arabic peoples. Allah recited to Muhammad the Quran. And a 3rd religion emerged, Islam.
