This noun describes the action of pouring or sprinkling liquid onto something, particularly in ritual contexts. In the New Testament, it appears in Hebrews' description of the first Passover, where Moses instructed the Israelites to apply blood to their doorposts. The multilingual glosses uniformly emphasize sprinkling (Spanish 'rociadura', French 'aspersion', German 'Besprengung'), pointing to the ritual act of applying the blood that protected the firstborn from the destroyer. This word captures the physical liturgical action that becomes a powerful symbol of protection and deliverance.
