'May the flowing waters be auspicious to your body, and may those from wells be auspicious to you; / may the waters of the desert be auspicious to you, and may those from streams be auspicious to you; / may the waters of the sea be auspicious to you, and may those of rain be auspicious to you; / may frost shower auspiciousness upon you, and may hail fall down auspiciously'—[with these words] he sprinkles [it] over with water.
