The number seven was the general symbol for all association with God, and was the favorite religious number of Judaism, typifying the covenant of holiness and sanctification, and also all that was holy and sanctifying in purpose. The candlestick had seven lamps, and the acts of atonement and purification were accompanied by a sevenfold sprinkling. The establishment of the Sabbath, the Sabbatical year, and the year of jubilee was based on the number seven, as were the periods of purification and of mourning.
