Another (currently more usual) alleged derivation of JHVH, is from YaHWeH. This would mean: "He Who causes to exist and Who maintains in existence." That would emphasize not so much the unchangeability of God Himself from and unto all eternity (cf. Malachi 3:6) – but rather the dependent nature of all created existence upon the independent one true God’s Own Being. Cf. Psalm 33:6-9 & Romans 4:17 & Hebrews 11:3.
JeHoVaH and YaHWeH – as distinct from their transmitted mispronunciations as ’A:donaay – both imply much the same. God alone is; so He does not ex-sist (or de-pend on anything else). And all else is not, but only ex-sists in Him Who alone is (Genesis 2:4f & Acts 17:26-28 & Colossians 1:16-17). For He "alone is JEHOVAH." Psalm 83:18.
