One of the reforms of this time expressly attributed to Simon ben Shetach was the promotion of better instruction. In all large towns, high schools for the use of young men from the age of sixteen sprung up at his instance. But all study, we may presume, was entirely confined to the Holy Scriptures, and particularly to the Pentateuch and the study of the Law. Many details or smaller points in the Law which had been partly forgotten and partly neglected during the long rule of the Sadducees, that is to say, from Hyrcanus's oppression of the Pharisees until the commencement of Salome's reign, were once more introduced into daily life. Neglected customs were renewed with all pomp and solemnity, the days of their re-introduction being celebrated with rejoicing, and any public mourning or fast thereon was suspended. Thus the ceremony of pouring a libation of water upon the altar during the Feast of Tabernacles, which had been mockingly ridiculed by Alexander, was in time reinstated with enthusiasm, and became a favorite and distinctive rite. Upon these occasions, on the night succeeding the first day of the festival, the women's outer court of the Temple was brilliantly illuminated until it glowed like a sea of fire. All the people would then crowd to the holy mount to witness or take part in the proceedings. At times these bore a lively character, such as torch-light processions and dancing; at others they took the more solemn form of musical services of song and praise. This jubilee would last the whole night. At break of day the priests announced with a blast of their trumpets that the march was about to commence. At every halting-place the trumpets gathered the people together, until a huge multitude stood assembled round the spring of Siloah. Thence the water was drawn in a golden ewer. In solemn procession it was carried back to the Temple, where the libation was performed. The water streamed over the altar, and the notes of the flute, heard only upon the most joyful occasions, mingled with the rapturous strains of melody that burst from countless instruments.
