(New International Version)

'Then she shall remain in the blood of her purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed.

And she shall then continue in the blood of her purifying three and thirty days; she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled.
