Merciful. — Literally, propitious. On the kindred word “make propitiation,” see Hebrews 2:17.
To their unrighteousness. — Rather, to their unrighteousnesses, and their sins will I remember no more. The words “and their iniquities” are omitted by the best authorities. Here is given the third and chief promise: the characteristic of the new covenant is the full pardon of sin.
Of this new covenant, “ordained” on the three promises of an inward revelation, universal knowledge of God, and free pardon of sin, Jesus is the Mediator. How this is to be understood the writer himself will teach, for all these promises are present (virtually or formally) in the last portion of his argument (Hebrews 10:14-18). In part they belong to the new covenant from the beginning. The pardon is spoken of not as a gift to individuals, but rather as from the first a characteristic of the covenant (Hebrews 9:26; Hebrews 10:18). The first promise is seen in the gift of the Holy Spirit, and in the teaching represented by the Sermon on the Mount, in which inward principles of life take the place of many an outward rule. The second waits for full accomplishment, but is seen in the abolition of distinctions between nation and nation, and the common influence of the Holy Spirit.
This subject has presented difficulties, because it has been forgotten that this Scripture speaks of no sudden change in man’s relation to God. The essential promises of the new covenant were not unknown under the old. “Thy law is within my heart” is the saying of one Psalmist; “Thou forgavest the iniquity of my sin,” of another. But in regard to the nation there was failure. The rites of the Law did not lead to the perception of spiritual truths; ordinances which were intended to teach the divine intolerance of sin became mere ceremonies; external sanctions did not preserve the nation in true obedience to God’s law. To all, the former covenant (like the first Tabernacle, Hebrews 9:9) was a parable, explained only when the new covenant (which was in truth before the old, Galatians 3:17) was “ordained.”
