What is the Hebrew prayer for water?

Answer 1

ברוך אתה ה׳ אלוקי×?ו מלך העולם, שהכול ×?×”×™×” בדברו׃

Ba-ruch a-tah A-do-nai E-lo-hei-nu Me-lech Ha-o-lam, she-ha-kol ni-h'yeh bid-va-ro.

Blessed are You, Eternal, our God, Ruler of the Universe, by whose word everything comes to be.

This is a "catch-all" blessing. Any snack item not covered by a more specific bessings is covered by this one.

One only makes a Shehakol before drinking water if one drinks to quench one's thirst or assist digestion.

The source is found in Gemara Brachot 44 and Rambam (Brachot 8:1). Buir Halacha 204:& D"H HaShoteh writes that drinking water in order to assist digestion is equivlant to dirnking for thirst.

The Bracha Achrona on water also depnds on whether one is thirsty or not as rules the S"A 204:7 (see Sh"t Shevet HaLevi 9:42 who writes that the Ashel Avraham who writes that one always makes a Bracha Achrona is error.)

However if one drinks water for any other reason such as to swallow a pill or food, for medical purposes, to clear one's throat, no bracha is required. If there is any doubt, it's a simple matter to just drink a little more and then say the blessings.

Answer 2

There is no such concept in the Jewish religion, but you can translate it literally as מי רוח (mei-ruach) which means "water of a spirit".
