Galatians 3:12

The law is not of faith. — The ruling principle of the Law is not faith, but something else — works.

The man that doeth them. — By “them” is meant the “statutes” and “judgments” mentioned immediately before in the verse (Leviticus 18:5) from which the quotation is taken. Just as the stress was upon “faith” in the last verse, so here it falls on the word “doeth:” it is a matter of works.

Shall live. — The idea of life receives an enlargement, corresponding to the fuller revelation of immortality in the New Testament as compared with the Old. In the Old Testament, “life is an existence upon earth, shortened by no judgment, reposing upon God, and delighting itself in God.” On the other hand, “death is the sudden and dreadful end, the destruction of this existence through a judgment of some special kind” (Schultz, Theology of the Old Testament, 2:163). Such a judgment would be the Chaldean invasion; and when the prophet Habakkuk says that the “just shall live,” he means that he should be saved from this calamity, and still continue to enjoy the divine favour and protection. The promise in Leviticus declares that he who keeps the Law shall be preserved from all judgments of this kind. With St. Paul, as in the Old Testament, the root idea is that of drawing support and sustenance from God; but with him this is not confined to the present life, or extended beyond the grave only in some dim and shadowy way: it begins in time and stretches on into eternity.

In them. — His life shall spring out of them and be nourished by them, just as a tree strikes its roots into the earth.
