The animals, in which these two characteristics met, were reckoned clean, and therefore fit for food. It is certain that the minute particularity of these words has some further reference than to the diet of Israel, important though that was, or to accentuate with every meal the necessity of their being a separate people. We, at least, may gather this lesson, that in our daily experience we must combine meditation and separation.
Meditation. - The cattle do not simply browse on the pastures, but they lie down to chew the cud. It is not enough to peruse our allotted Scripture portion; we must ruminate upon it, comparing spiritual things with spiritual, and scripture with scripture. The Holy Ghost will take of the things of Christ and show them unto us, and He will bring all things to our remembrance.
Separation. - "Whosoever doeth not righteousness is not of God." "The Word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." We have not meditated to good purpose unless we have felt its keen edge. Detachment from the world must follow on true attachment to Christ. Love to Naomi will draw Ruth from Moab across the Jordan.
The two must be combined. - The swine divideth the hoof, but cheweth not the cud, and was therefore unclean. A man may profess to love his Bible, but the supreme test is his daily separation from evil. On the other hand, our daily life ought to emanate, not from without, which is Pharisaism, but from within, where we chew the cud of holy meditation.
