Appropriately, Paul mentions both blood and flesh when describing how Jesus gave up his human existence for his disciples, thus opening up the way to gain life in heaven, the “way of entry into the holy place by the blood of Jesus, which he inaugurated for us as a new and living way through the curtain, that is, his flesh.”—1 Tim. 2:5, 6; 1 Cor. 15:45; Deut. 12:23; Lev. 17:11; Eph. 1:7; Heb. 10:19, 20.
... At the same time they were forbidden to offer sacrifices to demons at their table, as did the surrounding nations, who practiced false religion.—Lev. 7:11-37; 17:5-7; Ex. 24:9-11; Ezek. 44:16.
