8 And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.

9 But it shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off: and he shall wash his clothes, also he shall wash his flesh in water, and he shall be clean.

10 And on the eighth day he shall take two he lambs without blemish, and one ewe lamb of the first year without blemish, and three tenth deals of fine flour for a meat offering, mingled with oil, and one log of oil.

11 And the priest that maketh him clean shall present the man that is to be made clean, and those things, before the Lord, at the door of the tabernacle of the congregation:

After the little ritual with the birds, the former leper would wholly wash himself. He would wash his clothes, his body, and even shave off all of his hair. He would be like a newborn again.

This born-again symbolism continues as we hear that the leper would wait eight days, then come to the tabernacle to make an offering. We only recently learned how eight days was exactly how long a newborn boy would wait before being circumcised, and afterwards both boy and girl children would be brought to the tabernacle to have offerings made, just like happens here with the leper.

As verse 11 says, the leper is being presented to the Lord at the tabernacle, that he might be welcomed back into the congregation, just as he would have been welcomed the first time at his birth. The leper is being reborn and reinstituted to the Israelite family, just as we are baptized, reborn, and reinstituted back to the family of God.
