This spray paint and stencil illustration quotes a line in the Amidah service, "Mashiv HaRuach U'Morid HaGeshem" ("Who causes the wind to blow and rain to fall"). Passover is "Chag HaAviv" or the "Holiday of Spring" and marks a turning point in the daily prayer service when, in the musaf service on the first day of Passover, this prayer for rain is replaced with the prayer for dew in a special prayer called Tefillat Tal.
