Kaiser writes, “The prohibition… has been explained since 1933 by a reference in a broken passage of a thirteenth-century B.C. Ugaritic text called 'The Birth of the Gods Pleasant and Beautiful' (text 52, line 14). It is generally agreed that the reference is to a fertility rite that entails boiling a kid in milk; but there is no sure reference to the milk of its mother in the broken Ugaritic text.” Kaiser, W.
