Proven enough?

I flow to where I can
Freely without a plan to lead,
Always a step ahead,
I’m one you gently thread on; weird,
A friend highly revered,
Looking harmless but feared, with more
To pour and for the shore,
Everywhere like a whore; tough, calm,
I’m in the Book of Psalms
Read of me in Islam – Water
Earth’s permanent squatter
With God’s imprimatur. Ample!
