Leviticus 20:20-22

²⁰He that doith fleischli knowyng with the wijf of `his fadris brother, ether of his modris brother, and schewith the filthe of his kyn, bothe schulen bere her synne, thei schulen die without fre children.

²¹He that weddith `the wijf of his brother, doith an vnleueful thing; he schewide `the filthe of his brother, he schal be without fre children.

²²Kepe ye my lawis and my domes, and do ye tho, lest the lond, in to which ye schulen entre and dwelle, caste out viliche also you.
