In the company of his brethren, whose hymn-singing continued without interruption, the blessed Alexander went all the way across the desert to arrive at Solomon's city—the city he built "in the wilderness," as it says in the Book of Kings, now called Palmyra. But when, from far away, the people of the city caught sight of the brethren drawing nearer in their numbers [....], they closed the gates. "Who could possibly feed all those men?" they said to one another. "If they come into our city, then all of us will starve."
At this, the holy man gave praise to God. "Trust in the Lord is better than trust in men," he said. "Take courage, brothers, for the Lord watches over us in unsuspected ways." And [sure enough,] the barbarians of those parts showed a humanitarian concern that was unparalleled. The brethren had abided in the desert for three days when, from a distance of four days' travel, there arrived a group of camel-riders sent to them by the Lord with supplies, in accordance with what the holy one had said. To God the brethren gave praise and thanks, and let others share in the bounty. It was so much more than they needed that they found themselves distributing the goods sent to them among the poor of that city.
Some eager members of the brethren formed a plan. As consolation for their recent sufferings, they wished to bring refreshment to the brethren in their great numbers, and so they disobeyed the holy one by preparing a mixed grill for the brethren's gustatory delight. But Alexander decided to give them a lesson in sublimating their woes. As soon as the feast was all prepared, he took up the parchments of the Holy Gospel as was his custom, saying "Glory to God in the highest, peace on earth, good will toward men," which was his habitual way of taking leave. With that, he gave word that the feast be left untouched, and went back on the road. And the brethren held back from all that was laid out for them, and got back on the road.
