And when she was in labor, one baby put out his hand; and the midwife took his hand and bound upon it a scarlet thread, saying, This baby was born first.
And afterward his brother who had the scarlet thread on his hand was born and was named Zerah [scarlet].
As for the living bird, he shall take it, the cedar wood, and the scarlet [material], and the hyssop, and shall dip them and the living bird in the blood of the bird killed over the running water;
He shall take to cleanse the house two birds, cedar wood, scarlet [material], and hyssop;
Then the priest shall command to take for him who is to be cleansed two living clean birds and cedar wood and scarlet [material] and hyssop.
