The Hebrew verb zaraq means to sprinkle or toss something — typically blood or water — in a ceremonial act of consecration or purification. It is a key term in Levitical ritual law.
Zaraq is a technical term in the sacrificial system. Priests sprinkled (zaraq) blood against the altar to consecrate offerings and atone for sin (Leviticus 1:5, 11). It signifies the outward ritual act that points to inner cleansing. The prophets later proclaimed that God himself would sprinkle clean water upon his people in the new covenant (Ezekiel 36:25). The New Testament fulfillment is found in the 'sprinkling of the blood of Jesus Christ' (1 Peter 1:2).
