"Tu feras une cuve de cuivre, avec son support en cuivre, pour les ablutions; tu la placeras entre la Tente d’assignation et l’autel et tu y mettras de l’eau.
Mishnah Middot
The laver was between the porch and the altar, a little to the south. Between the porch and the altar there were twenty-two cubits. There were twelve steps there, each step being half a cubit high and a cubit broad. There was a cubit, a cubit and a level space of three cubits, then a cubit, a cubit and a level space of three cubits, then at the top a cubit, a cubit and a level space of four cubits. Rabbi Judah says that at the top there was a cubit, a cubit and a level space of five cubits.
