Leviticus 15:22-25

²²Who euer touchith ony vessel on which sche sittith, he schal waische hise clothis, and he schal be waischun in watir, and schal be defoulid `til to euentid.

²⁴If a man is couplid fleischli with hir in the tyme of blood that renneth bi monethis, he schal be vncleene bi seuene daies, and ech bed in which he slepith schal be defoulid.

²⁵A womman that suffrith in many daies the `fletyng out of blood, not in the tyme of monethis, ethir which womman ceessith not to flete out blood aftir the blood of monethis, schal be vncleene as longe as sche `schal be suget to this passioun, as if sche is in the tyme of monethis.
