Ezequiel 43

For seven days they are to make offerings to take away sin from the altar and to make it clean; so they are to make it holy.

Por siete días expiarán el altar, y lo limpiarán, y ellos henchirán sus manos.

Seven days shall they purge the altar and purify it; and they shall consecrate themselves.

Seven days shall they make atonement for the altar and purify it. So shall they consecrate it.
