Speak to Aaron, and thou shalt say to him: When thou shalt place the seven lamps, let the candlestick be set up on the south side. Give orders therefore that the lamps look over against the north, towards the table of the loaves of proposition, over against that part shall they give light, towards which the candlestick looketh.
