士師記 13:6 猶太思想：Guide for the Perplexed

We have already stated that the forms in which angels appear form part of the prophetic vision. Some prophets see angels in the form of man, e.g., “And behold three men stood by him” (Gen. 18:2); others perceive an angel as a fearful and terrible being, e.g., “And his countenance was as the countenance of an angel of God, very terrible” (Judges 13:6); others see them as fire, e.g., “And the angel of the Lord appeared to him in a flame of fire” (Exod. 3:2). In Bereshit Rabba (chap. l.) the following remark occurs: “To Abraham, whose prophetic power was great, the angels appeared in the form of men; to Lot, whose power was weak, they appeared as angels.” This is an important principle as regards Prophecy; it will be fully discussed when we treat of that subject (chap. xxxii. sqq.). Another passage in Bereshit Rabba (ibid.) runs thus: “Before the angels have accomplished their task they are called men, when they have accomplished it they are angels.” Consider how clearly they say that the term “angel” signifies nothing but a certain action, and that every appearance of an angel is part of a prophetic vision, depending on the capacity of the person that perceives it.
