On the day of their departure, the whole school came together, in the room of the teachers, for the parting prayer. All was silent, till the three asked to go and bid a farewell to their closets. They went, and only He who seeth in secret knows how they prayed. They returned weeping. A few words of comfort were uttered, and the teachers commended them to God. They rose from their knees, but only to kneel again; for one of the pupils proposed that all who would pledge themselves to remember their Tiary sisters in every prayer should join hands around them, commend them to the good Shepherd, and give to him their pledge. About twenty thus enclosed the departing sisters, and so they continued in prayer until the last moment. As the dear ones passed out, they could not speak, they whispered but one word,--"the promise,"--and so they went. For years after, no prayer was heard within those walls that did not contain a petition for "blessings on our Tiary sisters." Many a time had her teacher noticed the large folio page of Sarah's Syriac Testament wet with her tears, and after she left, found the whitewash of the wall in her closet furrowed with the same. It opened out of the passage behind the door on the left of the engraving. She did not tell this to the school, lest superstition should attach an idolatrous sacredness to the place; and yet she could not obliterate marks that to her own heart were so full of comfort. Sarah had gone but a little way before she pleaded with her parents to stop, and allow her to retire a little from the road for prayer. And so, weeping and praying as they went, these lambs were led into the dark recesses of a den of lions. We shall see persecution raging, pitiless as the mountain storm, and long continued. But we shall also see the Hearer of prayer preserving them unharmed; and if we hear more from the others than from Sarah, it may be that the revelation of the answers to her prayers is reserved for that day which shall unfold displays of grace too glorious for comprehension here. Nothing was heard from them till October, 1850, when Yonan and Khamis entered those rocky fastnesses to gather tidings of them. They spent the first Sabbath of the month in the house of Nazee; but she was absent. They say in their journal,--
