Yahweh IS Liberty!
Yahweh = Self-Existence (The True Name Of God).
Yah is short version of Yahweh (Think Nick 4 Nicholas).
Yahshuah (Self-Existence Saves) is the proper name of Messiah (Anointed Of Self-Existence) the name of the Incarnate Word & Son of Yahweh God, & the name above all names.
The Word/Son of Yahweh God had to incarnate in order to save humanity both spiritually & physically, to preserve perfect human genetics for eternity. Book of Enoch says Satan genetically vandalized creation, hence Flood.
