Luke 21:18

Jesus promised that He would keep them safe. This probably means that no harm would befall them without the Father’s permission (Luke 21:16; cf. Acts 27:34). [Note: Geldenhuys, p. 527; Morris, p. 298; Lenski, p. 1017.] Some interpreters believe it refers to their spiritual safety. [Note: E.g., Plummer, p. 480; Marshall, The Gospel . . ., p. 769; A. T. Robertson, Word Pictures in the New Testament, 2:259; H. A. Ironside, Addresses on the Gospel of Luke , 2:619; Liefeld, "Luke," p. 1021; and G. Campbell Morgan, The Gospel According to Luke, p. 237.] However physical safety seems to be in view throughout the passage.
