This is another meditation, together with a prayer of a righteous one set in the midst of abounding evil; and that evil is evidently the evil that is to be ripe and full in the last days, as we have just seen anticipated in the preceding Psalm. Infidel scoffing (such as that foretold as marking the last days, 2 Peter 3) is the principal feature of it. The mourner, however, hears in spirit the Lord’s answer to his prayer (Psa. 12:5); then celebrates the faithfulness of His words, that they were all tried and proved words; and finally professes his assurance that God’s faithfulness will prevail even in the worst of times.
“This generation” in Psalm 12:7 is described in Psalm 12:8. This word is, therefore, used in a moral sense; indeed it must be so used from the force of the words “forever.”
The people or generation with which both the Lord Jesus and the Remnant contend in their several days, are morally one and the same “generation.” And from this we can interpret Matthew 24:34 in a moral way. Perhaps there is tacit reference there to this passage.
