Psalms 7:9

7:1-9 David flees to God for succour. But Christ alone could call on Heaven to attest his uprightness in all things. All His works were wrought in righteousness; and the prince of this world found nothing whereof justly to accuse him. Yet for our sakes, submitting to be charged as guilty, he suffered all evils, but, being innocent, he triumphed over them all. The plea is, For the righteous God trieth the hearts and the reins. He knows the secret wickedness of the wicked, and how to bring it to an end; he is witness to the secret sincerity of the just, and has ways of establishing it. When a man has made peace with God about all his sins, upon the terms of grace and mercy, through the sacrifice of the Mediator, he may, in comparison with his enemies, appeal to God's justice to decide.

Psalm 7:9 . Let the wickedness of the wicked come to an end — Let the malice of mine enemies cease: put a stop to their wicked practices, either by changing their hearts or tying their hands: say to it as thou dost to the sea, Hitherto hast thou gone, but thou shalt advance no further. Hebrew, The wickedness of the wicked shall have an end; it shall cease: it shall be rooted out and destroyed. But establish the just — Or, And thou wilt establish, or confirm, or uphold the just, all just persons and causes; which is opposed to wickedness coming to an end, last mentioned. For the righteous God trieth the hearts and reins — And, therefore, he knows the secret wickedness of the wicked, and how to bring it to an end; and he is a witness to the secret sincerity of the just, and has secret ways of establishing them in it. “It is predicted, that wickedness will, in the end, be abolished, and the just immoveably established, by Him who knoweth intimately the very thoughts and desires of both good and bad men, and will give to each their due reward. How can we doubt of this when it has pleased God to afford so many examples and preludes to it in his dispensations of old time? The righteous cause hath already triumphed in Christ; let us not doubt that it will do so in the church. Happy the man whose hope is therefore in God, because he saveth the upright in heart.” — Horne.

Let the malice of mine enemies cease, put a stop to their wicked practices, either by changing their hearts, or by tying their hands, or some other way; say to it, as thou dost to the sea, Hitherto hast thou gone, but thou shalt go no further, and here shall thy proud waves be stayed. Or, The wickedness of the wicked shall have an end; not an end of perfection, which is to be accomplished; but all end of termination, it shall cease; and an end of destruction, it shall be rooted out. Or, Let, I pray thee, wickedness consume the wicked , i.e. those that are maliciously and incorrigibly such. And so this prayer is opposed to that following prayer for the just. And such prayers against some wicked men we find used by prophetical persons, which are not rashly to be drawn into precedent by ordinary persons. Establish; or, and thou wilt establish , or confirm , or uphold ; which is opposed to that coming to an end or consuming last mentioned. The just; all just persons and causes, and mine in particular, which is so. The righteous God trieth the heart and reins; and therefore he knows that I have not so much as a thought or a desire of that mischief which Cush and others report I am designing against Saul.

9 . More exactly: O that the evil of wicked men might come to an end, and that thou wouldest establish the righteous; For a trier of hearts and reins is God the righteous. The last clause adds the ground upon which the hope and prayer of the first clause is based. God is righteous, and He is a discerner of hearts; there can therefore be no doubt of His will and His ability to distinguish between the righteous and the wicked by an impartial judgement. Cp. 1 Samuel 16:7 ; Isaiah 11:3-4 . According to the ancient exegetical tradition represented by the Hebrew accents (Wickes’ Treatise on the Accentuation &c., p. 43), the first clause should be rendered, O let evil make an end of the wicked , and it is certainly a striking truth that the punishment of the wicked springs out of their own misdeeds: comp. Psalm 7:14 ff., and perhaps Psalm 34:21 : but the sense given by the LXX, Jerome, and the English Versions is probably right. trieth the hearts and reins ] A favourite thought with Jeremiah: see ch. Jeremiah 11:20 , Jeremiah 17:10 , Jeremiah 20:12 ; cp. Revelation 2:23 . The heart is regarded in the O.T. as the organ of thought and will, which determines the man’s moral and religious character, the reins (kidneys) as the seat of the emotions: see Delitzsch, Biblical Psychology , § xiii.; and Oehler, Old Testament Theology , § 71. 9, 10 .

Oh let the wickedness of the wicked come to and end - Of all the wicked; wickedness not in this particular case only, but wickedness of all forms, and in all lands. The prayer here is a natural one; when a man becomes impressed with a sense of the evil of sin in one form, he wishes that the world may be delivered from it in all forms and altogether. But establish the just - The righteous. This stands in contrast with his desire in regard to the wicked. He prays that the righteous may be confirmed in their integrity, and that their plans may succeed. This prayer is as universal as the former, and is, in fact, a prayer that the world may come under the dominion of the principles of truth and holiness. For the righteous God trieth the hearts and reins - That is, the hearts and reins of all people. He understands the character of all people; he is intimately acquainted with all their thoughts, and purposes, and feelings. To search or try "the heart and the reins" is an expression frequently used in the Bible to denote that God is intimately acquainted with all the thoughts and feelings of people; that is, that he thoroughly understands the character of all people. The word "heart" in the Scriptures is often used to denote the seat of the "thoughts;" and the word "reins" seems to be used to denote the most secret feelings, purposes, and devices of the soul - as if lodged deep in our nature, or covered in the most hidden and concealed portions of the man.

The word "reins," with us, denotes the kidneys. In the Scriptures the word seems to be used, in a general sense, to denote the inward parts, as the seat of the affections and passions. The Hebrew word כליה kilyâh, means the same as the word "reins" with us - the kidneys, Exodus 29:13, Exodus 29:22; Job 16:13; Isaiah 34:6; Deuteronomy 32:14. From some cause, the Hebrews seem to have regarded the "reins" as the seat of the affections and passions, though perhaps only in the sense that they thus spoke of the "inward" parts, and meant to denote the deepest purposes of the soul - as if utterly concealed from the eye. These deep thoughts and feelings, so unknown to other people, are all known intimately to God, and thus the character of every man is clearly understood by him, and he can judge every man aright. The phrase used here - of trying the hearts and reins - is one that is often employed to describe the Omniscience of God. Compare Jeremiah 11:20; Jeremiah 17:10; Jeremiah 20:12; Psalm 26:2; Psalm 139:13; Revelation 2:23. The particular idea here is, that as God searches the hearts of all people, and understands the secret purposes of the soul, he is able to judge aright, and to determine correctly in regard to their character, or to administer his government on the principles of exact justice.
