Here is a rough translation of the Hebrew words of the song you sang on the bus:
Draw water, With joy,
From the well of salvation.
Draw water, with joy,
From the well of Salvation.
Water, Water, Water, Water!
Hey! Water...with Joy!
Water, Water, Water, Water!
Hey! Water...with Joy!
Hey! Hey! Hey! Hey!
Water, Water,
Water, Water,
Water, Water,
Draw with Joy!
G-r-e-a-t!!! Thanks!!
