Immortality—perpetuity of existence. The doctrine of immortality is taught in the Old Testament. It is plainly implied in the writings of Moses (Gen. 5:22, 24; 25:8;37:35;47:9;49:29, comp. Heb. 11:13-16; Ex. 3:6, comp. Matt. 22:23). It is more clearly and fully taught in the later books (Isa. 14:9; Ps. 17:15;49:15;73:24). It was thus a doctrine obviously well known to the Jews.
With the full revelation of the gospel this doctrine was "brought to light" (2 Tim. 1:10; 1 Cor. 15; 2 Cor. 5:1-6; 1 Thess. 4:13-18).
