Barnes New Testament Notes

Verse 6. Give not that which is holy, etc. By some, the word holy has been supposed to mean flesh offered in sacrifice, made holy, or separated to a sacred use. But it probably means here anything connected with religion -- admonition, precept, or doctrine. Pearls are precious stones found in shell-fish, chiefly in India, in the waters that surround Ceylon. They are used to denote anything peculiarly precious, Re 17:4; 18:12-16; Mt 13:46.

In this place they are used to denote the doctrines of the gospel. Dogs signify men who spurn, oppose, and abuse that doctrine; men of peculiar sourness and malignity of temper, who meet it like growling and quarrelsome curs, 2 Pe 2:22; Re 22:15. Swine denote those who would trample the precepts under feet; men of impurity of life; corrupt, polluted, profane, obscene, and sensual; who would not know the value of the gospel, and who would tread it down as swine would pearls, 2 Pe 2:22; Pr 11:22. The meaning of this proverb then is, do not offer your doctrine to those violent and abusive men, who would growl and curse you; nor to those peculiarly debased and profligate, who would not perceive its value, would trample it down, and abuse you. This verse furnishes a beautiful instance of the introverted parallelism. The usual mode of poetry among the Hebrews, and a common mode of expression in proverbs and apothegms, was by the parallelism, where one member of a sentence answered to another, or expressed substantially the same sense with some addition or modification. See my Introduction to Isaiah. Sometimes this was alternate, and sometimes it was introverted -- where the first and fourth lines would correspond, and the second and third. This is the case here. The dogs would rend, and not the swine; the swine would trample the pearls under their feet, and not the dogs. It may be thus expressed:

Give not that which is holy unto the dogs.

Neither cast ye your pearls before swine,

Lest they trample them under their feet,

And turn again [that is, the dogs] and rend you.

{u} "neither cast ye your" Pr 9:7,8; 23:9
