The week of this festival, commencing with the paschal sacrament, was made to bear peculiarly on the national life, first by the command that all leaven should be rigidly kept out of the houses. As the ceremonial law assumed more importance with the growth of Pharisaism, this cleansing was sought quite fanatically. Any crumb of common bread was reckoned an accursed thing which might deprive the observance of the feast of its good effect. But even in the time of less scrupulous legalism the effort to extirpate leaven from the houses had its singular effect on the people. It was one of the many causes which made Jewish religion intense. Then the daily sacrificial routine, and especially the holy convocations of the first and seventh days, were profoundly solemnising. We may picture thus the ceremonies and worship of these great days of the feast. The people, gathered from all parts of the land, crowded the outer court of the sanctuary. The priests and Levites stood ready around the altar. With solemn chanting the animals were brought from some place behind the temple where they had been carefully examined so that no blemish might impair the sacrifice. Then they were slain one by one, and prepared, the fire on the great altar blazing more and more brightly in readiness for the holocaust, while the blood flowed away in a red stream, staining the hands and garments of those who officiated. First the two bullocks, then the ram, then the lambs were one after another placed on the flames, each with incense and part of the meal offering. The sin offering followed. Some of the blood of the he-goat was taken by the priest and sprinkled on the inner altar, on the veil of the Holy of Holies, and on the horns of the great altar, around which the rest was poured. The fat of the animal, including certain of the internal parts, was thrown on the fire; and this portion of the observances ended with the pouring out of the last drink offering before the Lord. Then a chorus of praise was lifted up, the people throwing themselves on the ground and praying in a low, earnest monotone. To this followed in the later times singing of chants and psalms, led by the chorus of Levites, addresses to the people, and shorter or longer prayers to which the worshippers responded. The officiating priest, standing beside the great altar in view of all, now pronounced the appointed blessing on the people. But his task was still not complete. He went into the sanctuary, and, having by his entrance and safe return from the holy place shown that the sacrifice had been accepted, he spoke to the assembly a few words of simple and sublime import. Finally, with repeated blessing, he gave the dismissal. On one or both of these occasions the form of benediction used was that which we have found preserved in the sixth chapter of this book.[13]
