Leviticus 13 governs examination and declaration; Leviticus 14 governs restoration/cleansing after the condition resolves and extends the affliction category to houses. Chapter 13 determines the condition and status; chapter 14 begins only after healing and governs the person’s return to ordinary community and sanctuary life.

Both rituals use paired animals in which one is killed and the other is sent away alive, creating a strong purification/disposal pattern without making the bird rite identical to the Day of Atonement goats.

Leviticus 14 uses cedar wood, scarlet material, hyssop, running water, and sprinkling in the purification ritual after a serious skin affliction. Numbers 19 uses cedar, hyssop, scarlet, water, and sprinkling in the red-heifer purification rite for corpse impurity. The repeated material vocabulary shows a shared purification world while the two rituals remain distinct in purpose and procedure.

Psalm 51's 'purge me with hyssop' draws on biblical purification practice; Leviticus 14 is one important hyssop-purification context but cannot be proved as the psalm's exclusive source.
