Let them be before the Lord continually - Let their sins never pass from the mind of God. Let him never so forget them as not to inflict punishment for them.

That he may cut off the memory of them from the earth - That they may be wholly forgotten among people. Let their very name perish; and let the offender in this case be in the condition of those who have no ancestors to whom they can refer with pride and pleasure. The idea here is drawn from the honor which is felt in being able to refer to ancestors worthy of being remembered for their virtues.

Let them be before the Lord continually,.... And not cast behind his back, or into the depths of the sea, never to be seen more, as sins are when forgiven; but be always in sight, as loathsome and abominable, and causing those that committed them to be abhorred for them; and be before him, as a Judge, to examine them, the nature and kind of them, and to condemn and punish for them; see Exodus 20:5. The Targum is,

"let them be before the Word of the Lord always;''

see Hebrews 4:13.

That he may cut off the memory of them from the earth; so that they may not be remembered with any applause, or their name spoken of with any commendation; see Job 18:17.

Let them be before the LORD continually, that he may cut off the memory of them from the earth.

109:6-20 The Lord Jesus may speak here as a Judge, denouncing sentence on some of his enemies, to warn others. When men reject the salvation of Christ, even their prayers are numbered among their sins. See what hurries some to shameful deaths, and brings the families and estates of others to ruin; makes them and theirs despicable and hateful, and brings poverty, shame, and misery upon their posterity: it is sin, that mischievous, destructive thing. And what will be the effect of the sentence, Go, ye cursed, upon the bodies and souls of the wicked! How it will affect the senses of the body, and the powers of the soul, with pain, anguish, horror, and despair! Think on these things, sinners, tremble and repent.
