When Moses was in heaven, God showed him the Tabernacle, as well as models for all the holy vessels therein, hence Moses naturally supposed that he was destined to be the builder of the Tabernacle. But he was mistaken, for when he was about to leave heaven, God said to Moses: "Thee have I appointed king, and it does not behoove a king to execute works in person, but to give people directions. Therefore thou are not to execute the building of the Tabernacle in person, but thou art to give them thy directions to be executed."
Moses now asked God whom he should select as the man to carry out his orders, whereupon God fetched out the book of Adam and laid it before Moses. In this book he found recorded all the generations, from the creation of the world to the resurrection of the dead, and the kings, leaders, and prophets set down beside every generation. Then God said to Moses: "In that hour did I decree every man's calling, and Bezalel was then appointed to his task."
