Leviticus 13:11

it is a chronic ¹  disease on the skin of his body, ²  so the priest is to pronounce him unclean. ³  The priest ⁴  must not merely quarantine him, for he is unclean. ⁵ 

¹ tn The term rendered here “chronic” is a Niphal participle meaning “grown old” (HALOT 448 s.v. II ישׁן nif.2). The idea is that this is an old enduring skin disease that keeps on developing or recurring.

² tn Heb “in the skin of his flesh” as opposed to the head or the beard (v. 29; cf. v. 2 above).

³ tn This is the declarative Piel of the verb טָמֵא (tame’, cf. the note on v. 3 above).

⁴ tn Heb “he”; the referent (the priest) has been specified in the translation for clarity.

⁵ sn Instead of just the normal quarantine isolation, this condition calls for the more drastic and enduring response stated in Lev 13:45-46. Raw flesh, of course, sometimes oozes blood to one degree or another, and blood flows are by nature impure (see, e.g., Lev 12 and 15; cf. J. E. Hartley, Leviticus [WBC], 191).
