וְשִׁלַּ֞ח אֶת־הַצִּפֹּ֧ר הַֽחַיָּ֛ה אֶל־מִח֥וּץ לָעִ֖יר אֶל־פְּנֵ֣י הַשָּׂדֶ֑ה וְכִפֶּ֥ר עַל־הַבַּ֖יִת וְטָהֵֽר׃
But he shall let go the living bird out of the city into the open field; so shall he make atonement for the house; and it shall be clean.
Targum Jonathan on Leviticus
And the living bird he shall send forth out of the town upon the face of the field, and shall atone for the house, and it shall be clean. But if it is to be that the house will be again struck with leprosy, the bird on that day will return, and may be fit for food. But the bird that was killed shall the priest bury in the presence of the owner of the house.
