2 Chronicles 30:16

16. They stood in their place after their manner Priest and Levite occupied each his prescribed place, and performed each his prescribed work according to the law the priests to sprinkle the blood, (see Leviticus 1:5; Leviticus 3:2,) the Levites to assist in any work that might be required. In the present instance the Levites killed the paschal victims. 2 Chronicles 30:17. “According to the Mishna, the custom was for the priests to stand in two rows extending from the altar to the outer court, where the people were assembled. As each offerer slew his lamb the blood was caught in a basin, which was handed to the nearest priest, who passed it on to his neighbour, and he to the next; the blood was thus conveyed to the altar, at the base of which it was thrown by the last priest in the row. While basins full of blood were thus passed up, empty basins were passed down in a constant succession, so that there was no pause or delay.” Rawlinson.
