Who has a voice like rushing waters?

Ezekiel 43:2 NWT

And I saw the glory of the God of Israel coming from the east, and his voice was like the sound of many waters, and the earth began to shine because of his glory.

Revelation 1:15-18 NWT

“His feet were like fine copper when glowing in a furnace; and his voice was like the sound of many waters. And he had in his right hand seven stars, and out of his mouth a sharp, long, two-edged sword was protruding, and his countenance was like the sun when it shines at its brightest. When I saw him, I fell as dead at his feet. And he laid his right hand on me and said: ‘Do not be afraid. I am the First and the Last, and the living one, and I became dead, but look! I am living forever and ever, and I have the keys of death and of the Grave.'”
