You shall not seethe a kid in his mother's milk.

Exodus 23:19. You shall not seethe a kid in his mother's milk. It is suggested that the command has reference to a superstitious practice customary at the close of the harvest—a kid being then boiled in its mother’s milk with magic rites, and the milk used to sprinkle plantations, fields, and gardens, in order to render them more productive the next year (Ellicott). People of God must believe that obedience to the Law is the way for the blessing of milk and honey on the promised land. Pagans used to boil a kid in its mother’s milk, and “to sprinkle the trees, and fields, and gardens, with the broth in a magical manner, to make them more fruitful the following year.” It is also related with offering any animal in sacrifice when it was milky and unformed, or before it was eight days old. And it is chiefly intended, like many other of God’s laws, to prevent cruelty toward the creatures, and to inculcate a mild and tender disposition of God’s people (Benson). It in connection with the prohibitions to slaughter a cow and a calf, or an ewe and her lamb, on the same day (Lev 22:28), or to take a bird along with her young in the nest (Deut 22:6). It is thus understood as a protest against cruelty and outraging the order of nature
