Isaiah 5:26

Isaiah 52:6
King James Version (KJV)

6 Therefore my people shall know my name: therefore they shall know in that day that I am he that doth speak: behold, it is I.

“hayah or hayaw” meaning “to be or exist”, AH in hebrew means a first or singular person, hence AH-Hayah means that I EXIST, or I BE, or I AM, so this is how you know the true name of the Most High, I AM = AHAYAH.
