The Lord spake suddenly To stifle the beginnings of the sedition, that this example might not spread among the people, the divine voice from the Shechinah interrupts them in the midst of their dispute, commanding Aaron and his sister to come forth from their tents to meet Moses immediately at the door of the tabernacle, which they did accordingly. The Lord stood in the door While they stood without, Aaron not being admitted into the tabernacle as he used to be, a sign of God's displeasure.
