The significance of the Name of the heavenly ‘Elohiym:

YHWH, the I AM: (Replaced with Lord ~7000 times in scripture)

I AM THAT I AM or WILL BE, ETC.

“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 ‘the spirit’ (ha-ruwach: the expression of, the mind of, etc..), as also to say, the Word and Works of, the Bible’s true ‘Elohiym!

“I AM THAT I AM”…. Will You Be?
