Significance of the Name of the ‘Elohiym of Israel:
YHWH (I AM WHAT I AM):
“According to the Hebrew Bible, in the encounter of the burning bush (Exodus 3:14) Moses asks what he is to say to the Israelites when they ask what ‘gods’ (‘Elohiym) have sent him to them, and YHWH replies, “I am who I am”, adding, “Say this to the people of Israel, ‘I am has sent me to you.’ ”
The Name that is, ‘spirit’ (ruwach: the expression of,the mind of, etc..), the Word and Works of, Abraham’s‘Elohiym!
