Explanation of Numbers 18:19
By Henry MacLagan
Verse 19. In one word, all illustration in worship which the man of the Spiritual Church receives from the Lord must be ascribed to Him, even as to every perception of truth, and every delight in good, and this perpetually through the celestial heavens; for thereby is the reciprocal conjunction of good with truth and of truth with good between the celestial and spiritual man to eternity.

9417. 'And the law and the commandment' means truth in general and in particular. This is clear from the meaning of 'the law' as truth in general; and from the meaning of 'the commandment' as truth in particular. In the Word laws are divided up into commandments, judgements, and statutes, 'commandments' being used to mean laws of life, 'judgements' to mean laws of the civic state, and 'statutes' to mean laws of worship, 8972. However, all these together are called by the general term 'the law', and the individual requirements of the law are called 'commandments', as is clear from a large number of places in the Word. So it is that when the expression 'the law and the commandment' is used, truth in general and in particular is meant.
