(25) Ye shall therefore put difference.--Better, Ye shall therefore separate. It is the same word which is used at the end of the preceding verse, and which is rendered "separate" in the Authorised Version. It is important that the word should be translated by the same expression, since it not only shows the intimate connection between the two verses, but brings out more forcibly the reason for the exhortation in the verse before us. Because the Lord has separated or distinguished the Israelites from all nations, and is about to give them the promised land, therefore the Israelites are to separate or to distinguish between the clean and unclean animals, as ordained in Leviticus 11. By strictly following out the dietary laws, the Israelites will always be able to keep separate from all other nations (Daniel 1:8).

20:10-27 These verses repeat what had been said before, but it was needful there should be line upon line. What praises we owe to God that he has taught the evil of sin, and the sure way of deliverance from it! May we have grace to adorn the doctrine of God our Saviour in all things; may we have no fellowship with unfruitful works of darkness, but reprove them.Ye shall therefore put difference between clean beasts and unclean,.... The ten clean ones, as Aben Ezra observes, and all the rest that are unclean, according to the law before given, Leviticus 11:3, by using the one for food, and not the other, and so the Targum of Jonathan, ye shall separate between the beast which is fit for food, and that which is not fit for food:

and between unclean fowls and clean; and which the same Targum interprets, what is unfit to eat and what is fit, even all that are particularly mentioned as unclean, and not fit for food, in Leviticus 11:13 and all the rest not excepted to as clean and fit for food, which was one way and means God made use of to separate them from other nations, and so preserve them from their idolatrous and evil works:

and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground; that is, by eating them, contrary to the command of God, which would make them abominable in his sight; see Leviticus 11:43; every sin or transgression of this law being so to him:

which I have separated from you as unclean; which by law he had commanded them to abstain from the use of, as clean, and not fit to be eaten.
