Then came Amalek, and fought with Israel in Rephidim. And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek; to-morrow I will stand on the top of the hill with the rod of God in mine hand. So Joshua did as Moses had said to him and fought with Amalek; And Moses, Aaron, and Hur went up to the top of the hill. And it came to pass, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. But Moses' hands were heavy; and they took a stone and put it under him, and he sat thereon: and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side: And his hands were steady until the going down of the sun. And Joshua discomfited Amalek and his people with the edge of the sword.--_Exodus 17, 8-13._ An impressive picture of modern art is that which has for its scene the Evil One, the devil, sitting at a table playing a game of chess. Bending over the board, with the self-possession of a master, reclines the adversary of man. At the opposite side is a young man. There is a look of diabolical glee upon the dark brow of Satan, whilst the features of his playmate wear the signs of deepest agony; for, alas! that which the youth has staked on the results of the game seems hopelessly lost--his immortal soul. Back of the young man, unseen by him, the artist has painted a calm, benignant figure. It is his guardian angel, or better still, the Angel of the Covenant, the Lord, whose heavenly skill at last checkmates the destroyer. This is not merely poetic and artist's fancy. It is with no cloudy vagueness that the existence of a Spirit of Evil is revealed in the Holy Scriptures. There are many these days who are disposed to laugh at the account which tells us of man's temptation and fall in the Garden as a myth, an Oriental hyperbole, and to characterize the closing chapters of Revelation, which inform us of the Tempter's fall and fate, as allegory and romance. But there still remains scattered throughout the Bible, in connection with every prominent Bible character and Bible event, mention of a personal agent of evil, the foe of God and the foe of man, bent with restless activity and mastery of deceit upon the destruction of souls and the corruption of the creation of God. Not a matter of speculation is this belief in the existence and power of the chief of fallen angels, and far wiser and prudent were it if, in place of talking of, people, in humble acceptation of God's Word, would recognize their foe, and seek the strength and means to contend with him.
