On Sundays they halted and "lay off" all day. This was Dr. Gillespie's wish. He had told the young men at the start and they had agreed. It would be a good thing to have a day off for washing and general "redding up." But the doctor had other intentions. In his own words, he "kept the Sabbath," and each Sunday morning read the service of the Episcopal Church. Early in their acquaintance David had discovered that his new friend was religious; "a God-fearing man" was the term the doctor had used to describe himself. David, who had only seen the hysterical, fanaticism of frontier revivals now for the first time encountered the sincere, unquestioning piety of a spiritual nature. The doctor's God was an all-pervading presence, who went before him as pillar of fire or cloud. Once speaking to the young man of the security of his belief in the Divine protection, he had quoted a line which recurred to David over and over--in the freshness of the morning, in the hot hush of midday, and in the night when the stars were out: "Behold, He that keepeth Israel shall neither slumber nor sleep." Overcome by shyness the young men had stayed away from the first Sunday's service. David had gone hunting, feeling that to sit near by and not attend would offer a slight to the doctor. No such scruples restrained Leff, who squatted on his heels at the edge of the creek, washing his linen and listening over his shoulder. By the second Sunday they had mastered their bashfulness and both came shuffling their hats in awkward hands and sitting side by side on a log. Leff, who had never been to church in his life, was inclined to treat the occasion as one for furtive amusement, at intervals casting a sidelong look at his companion, which, on encouragement, would have developed into a wink. David had no desire to exchange glances of derisive comment. He was profoundly moved. The sonorous words, the solemn appeal for strength under temptation, the pleading for mercy with that stern, avenging presence who had said, "I, the Lord thy God am a jealous God," awed him, touched the same chord that Nature touched and caused an exaltation less exquisite but more inspiring. The light fell flickering through the leaves of the cotton-woods on the doctor's gray head. He looked up from his book, for he knew the words by heart, and his quiet eyes dwelt on the distance swimming in morning light. His friend, the old servant, stood behind him, a picturesque figure in fringed buckskin shirt and moccasined feet. He held his battered hat in his hand, and his head with its spare locks of grizzled hair was reverently bowed. He neither spoke nor moved. It was Susan's voice who repeated the creed and breathed out a low "We beseech thee to hear us, Good Lord."
