Meaning
(2.) The blood of sacrifices was caught by the priest in a basin, and then sprinkled seven times on the altar; that of the passover on the doorposts and lintels of the houses (Ex 12; Lev 4:5-7; 16:14-19). At the giving of the law (Ex 24:8) the blood of the sacrifices was sprinkled on the people as well as on the altar, and thus the people were consecrated to God, or entered into covenant with him, hence the blood of the covenant (Matt 26:28; Heb 9:19, 20; 10:29; 13:20).
(3.) Human blood. The murderer was to be punished (Gen 9:5). The blood of the murdered "crieth for vengeance" (Gen 4:10). The "avenger of blood" was the nearest relative of the murdered, and he was required to avenge his death (Num 35:24, 27). No satisfaction could be made for the guilt of murder (Num 35:31).
(4.) Blood used metaphorically to denote race (Acts 17:26), and as a symbol of slaughter (Isa 34:3). To "wash the feet in blood" means to gain a great victory (Ps 58:10). Wine, from its red colour, is called "the blood of the grape" (Gen 49:11). Blood and water issued from our Saviour's side when it was pierced by the Roman soldier (John 19:34). This has led pathologists to the conclusion that the proper cause of Christ's death was rupture of the heart. (Comp. Ps 69:20.)
