We have now reached the majestic Covenant Psalm, which, according to the Jewish arrangement closes the third book of the Psalms. It is the utterance of a believer, in the presence of great national disaster, pleading with his God, urging the grand argument of covenant engagements, and expecting deliverance and help, because of the faithfulness of Jehovah.

TITLE. Maschil. This is most fitly called a Maschil, for it is most instructive. No subject is more important or is so fully the key to all theology as that of the covenant. He who is taught by the Holy Spirit to be clear upon the covenant of grace will be a scribe well instructed in the things of the kingdom; he whose doctrinal theory is a mingle mangle of works and grace is scarcely fit to be the teacher of babes. Of Ethan the Ezrahite: perhaps the same person as Jeduthun, who was a musician in David's reign; was noted for his wisdom in Solomon's days, and probably survived till the troubles of Rehoboam's period. If this be the man, he must have written this Psalm in his old age, when troubles were coming thick and heavy upon the dynasty of David and the land of Judah; this is not at all improbable, and there is much in the Psalm which looks that way.

DIVISION. The sacred poet commences by affirming his belief in the faithfulness of the Lord to his covenant with the house of David, and makes his first pause at Ps 89:4. He then praises and magnifies the name of the Lord for his power, justice, and mercy, Ps 89:5-14. This leads him to sing of the happiness of the people who have such a God to be their glory and defense, Ps 89:15-18. He rehearses the terms of the covenant at full length with evident delight, Ps 89:19-37, and then mournfully pours out his complaint and petition, Ps 89:38-51, closing the whole with a hearty benediction and a double Amen. May the Holy Spirit greatly bless us the reading of this most precious Psalm of instructions

Verse 28. My mercy will I keep for him forevermore. The kings of David's line needed mercy, and mercy prevented their house from utterly perishing until the Son of Mary came. He needs no mercy for himself, but he is a representative man, and the mercy of God is required for those who are in him: for such mercy is kept forever. And my covenant shall stand fast with him. With Jesus the covenant is ratified both by the blood of sacrifice and by the oath of God, it cannot be canceled or altered, but is an eternal verity, resting upon the veracity of one who cannot lie. What exultation fills our hearts as we see that the covenant of grace is sure to all the seed because it stands fast with him with whom we are indissolubly united.
