There is a legend, that during the suffering of the Savior on the Cross, a certain Jacob received the blood and water flowing from the side of the Savior in a bowl (tikva) and kept this holy relic for himself. As if he didn't know, he poured olive oil over the blood in the bowl, and through the olive oil performed many healings. After the death of Jacob, this holy relic passed to two desert-dwellers, and on their death to Barypsabas. Adding olive oil to the blood of Christ, Barypsabas performed many healings. Evil people from self-interest killed the holy desert-dweller, took the bowl, but did not find in it what they expected.
