We do not read that Heraclius made an attempt to relieve Jerusalem, which yet was besieged during a year. Obeidah wrote to the patriarch and the inhabitants: “Salutation and blessing to all those who walk in the right way. We invite you to confess that there is only one God, and Mohammed is His Prophet. If you will not make this confession, then resolve to make your city tributary to the chalif. If you delay to do this, I will set my people upon you, who all love death more than you love wine and swine flesh. Hope not that I will draw away hence, until, if God please, I have killed all your warriors, and made slaves of your children.” The patriarch Sophronius negotiated without hope of earthly aid, and Obeidah, to save the Holy City, the cradle of prophets, from being desecrated by blood-shedding, yielded to the Christian wish that the chalif in person should be asked to receive the keys of the city, and regulate the conditions of surrender. And in 637 Chalif Omar came from Medina. As the Commander of the Faithful entered the city, he rode on a camel, clothed like the poorest Bedouin, and carrying on the same rough beast a sack of dates, rice, and bruised wheat or maize, also a water-skin, and a large wooden platter, on which he took his food with his companions. The terms of capitulation which he granted to the patriarch remained for long a standard to the Moslem in the like cases. First of all was the poll tax imposed by the Koran. The inhabitants to be protected and secured in life and property; their churches not to be pulled down, nor used by any but themselves. The Christians duly to pay tribute; to build no new churches either in the city or country; not to prevent Moslim by night or day from entering the churches. Their doors to be always open to travellers. The Christian to whom a traveller comes, shall entertain him three days gratis. Christians shall say nothing against the Koran. Shall prevent no one becoming Moslem. Shall show honour to Moslim. Shall not wear garments, or shoes, or turbans, like theirs. Shall not divide their hair like them. Shall not bear surnames like them. Shall not ride on saddles. Shall bear no arms, nor Arabic writing on their seals, nor give away wine, nor sell it. They shall wear the same kind of dress everywhere, and that with a girdle. They may have no slave who has served a Moslem. No crosses on the churches; nor ring bells, but only strike them. The chalif Omar caused himself to be led into all the holy places in the garb of a pilgrim by the patriarch Sophronius, even to the church of the Resurrection. There he placed himself on the floor, and the patriarch was most anxious lest he should practise his own acts of devotion there. With breaking heart the patriarch quoted to those around him the words of Daniel, “The abomination of desolation in the temple”.
