This well was in the shape of a sieve-like rock, out of which water gushes forth as from a spout. It followed them on all their wanderings, up hill and down dale, and wherever they halted, it halted, too, and it settled opposite the Tabernacle. Thereupon the leaders of the twelve tribes would appear, each with his staff and chant these words to the well, "Spring up, O well, sing ye unto it; nobles of the people digged it by the direction of the lawgiver with their staves." Then the water would gush forth from the depths of the well, and shoot up high as pillars, then discharge itself into great streams that were navigable, and on these rivers the Jews sailed to the ocean, and hauled all the treasures of the world therefrom.
