Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the Lord your God. Numbers 10:10.
The feast of Tabernacles was the closing gathering of the year. It was God’s design that at this time the people should reflect on His goodness and mercy.... From far and near the people came, bringing in their hands a token of rejoicing. Old and young, rich and poor, all brought some gift as a tribute of thanksgiving to Him who had crowned the year with His goodness, and made His paths drop fatness. Everything that could please the eye, and give expression to the universal joy, was brought from the woods; the city bore the appearance of a beautiful forest....
At the first dawn of day, the priests sounded a long, shrill blast upon their silver trumpets, and the answering trumpets, and the glad shouts of the people from their booths, echoing over hill and valley, welcomed the festal day.—The Desire of Ages, 447, 448.
The temple was the center of the universal joy. Here was the pomp of the sacrificial ceremonies. Here, ranged on either side of the white marble steps of the sacred building, the choir of Levites led the service of song. The multitude of worshipers, waving their branches of palm and myrtle, took up the strain, and echoed the chorus; and again the melody was caught up by voices near and afar off, till the encircling hills were vocal with praise.—The Desire of Ages, 448.
