He is thy life, and the length of thy days. — This is the Old Testament form of a well-known saying in the New Testament, which may yet be fulfilled in Israel, “I am the resurrection and the life. He that believeth in me, though he were dead, yet shall he live; and whosoever liveth and believeth in me shall never die” (John 11:25-26).
