For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.
ExplanationCommentary
Verse 12. For the word of God is living, and so forth Some understand by the word of God, the eternal word, or Son of God: (to whom may apply all in the 12th and 13th verses) but others rather expound it of the words, promises, and menaces of God, either foretold by the prophets, or preached by the apostles. Witham.—All this language is metaphorical, but perfectly well understood by the Jews. In their sacrifices, the Levites made use of a two-edged knife to separate from the victim what was for God, what was for the priests, and what was for the people. Thus in sacrificing sinners to the justice of God, Jesus Christ, like a two-edged knife, will separate what is for God, and what is for man; that is whatever is good or evil in the whole of man’s conduct.
