The Hebrew words Elohim and Adonai are applied to other things beyond the true and living God. There is, however, one name that is unique to the God of the Bible. This name is Yahweh. Yahweh refers to "the self-existent, eternal God," the name God revealed to Moses.
“You were shown these things so that you might know that the LORD is God; besides him there is no other.” -Deuteronomy 4:35
