Thrice he repeats the vow of praise. His harp was his companion in his flight, and even in the midst of peril the poet's nature appears which regards all life as materials for song, and the devout spirit appears which regards all trial as occasions for praise. He has calmed his own spirit, as he had done Saul's, by his song, and by prayer has swung himself clear above fightings and fears. The refrain, which occurs twice in the psalm, witnesses to the growth of his faith even while he sings. At first he could only say in patient expectance, "My strength! I will wait upon thee, for God is my fortress." But at the end his mood is higher, his soul has caught fire as it revolves, and his last words are a triumphant amplification of his earlier trust: "My strength! unto thee will I sing with the harp--for God is my fortress--the God of my mercy." V.--THE EXILE--_CONTINUED_. "So David fled, and escaped and came to Samuel to Ramah, and told him all that Saul had done unto him. And he and Samuel went and dwelt in Naioth" (1 Sam. xix. 18)--or, as the word probably means, in the collection of students' dwellings, inhabited by the sons of the prophets, where possibly there may have been some kind of right of sanctuary. Driven thence by Saul's following him, and having had one last sorrowful hour of Jonathan's companionship--the last but one on earth--he fled to Nob, whither the ark had been carried after the destruction of Shiloh. The story of his flight had not reached the solitary little town among the hills, and he is received with the honour due to the king's son-in-law. He pleads urgent secret business for Saul as a reason for his appearance with a slender retinue, and unarmed; and the priest, after some feeble scruples, supplies the handful of hungry fugitives with the shewbread. But David's quick eye caught a swarthy face peering at him from some enclosure of the simple forest sanctuary, and as he recognised Doeg the Edomite, Saul's savage herdsman, a cold foreboding of evil crept over his heart, and made him demand arms from the peaceful priest. The lonely tabernacle was guarded by its own sanctity, and no weapons were there, except one trophy which was of good omen to David--Goliath's sword. He eagerly accepts the matchless weapon which his hand had clutched on that day of danger and deliverance, and thus armed, lest Doeg should try to bar his flight, he hurries from the pursuit which he knew that the Edomite's malignant tongue would soon bring after him. The tragical end of the unsuspecting priest's kindness brings out the furious irrational suspicion and cruelty of Saul. He rages at his servants as leagued with David in words which have a most dreary sound of utter loneliness sighing through all their fierce folly: "All of you have conspired against me; there is none of you that is sorry for me" (1 Sam. xxii. 8.) Doeg is forward to curry favour by telling his tale, and so tells it as to suppress the priest's ignorance
