Can you post the verse where YHWH says that?
Act 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
Isaiah 49:26 And I will feed them that oppress thee with their own flesh; and they shall be drunken with their own blood, as with sweet wine; and all flesh shall know that I YHWH am thy Saviour, and thy Redeemer, the Mighty One of Jacob.
The only Saviour is YHWH.
Psa 3:8 Salvation belongeth unto the LORD:thy blessing is upon thy people.Selah.
Zec 9:9 Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he [is] just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.
The only Saviour is YHWH.
