Wherewith {k} thine enemies have reproached, O LORD; wherewith they have reproached the {l} footsteps of thine anointed.

(k) So he calls them who persecute the Church.

(l) They laugh at us who patiently wait for the coming of your Christ.

Wesley's Notes

89:51 Anointed - By whom he seems to understand either first the kings of Judah, the singular number being put for the plural; and by their footsteps may be meant either their ways or actions, or the memorials of their ancient splendor; or secondly the Messiah, whom the Jews continually expected for a long time, which being well known to many of the Heathens, they reproached the Jews, with the vanity of this expectation. And by the footsteps of the Messiah, he may understand his coming.

Matthew Henry's Concise Commentary

89:38-52 Sometimes it is not easy to reconcile God's providences with his promises, yet we are sure that God's works fulfil his word. When the great Anointed One, Christ himself, was upon the cross, God seemed to have cast him off, yet did not make void his covenant, for that was established for ever. The honour of the house of David was lost. Thrones and crowns are often laid in the dust; but there is a crown of glory reserved for Christ's spiritual seed, which fadeth not away. From all this complaint learn what work sin makes with families, noble families, with families in which religion has appeared. They plead with God for mercy. God's unchangeableness and faithfulness assure us that He will not cast off those whom he has chosen and covenanted with. They were reproached for serving him. The scoffers of the latter days, in like manner, reproach the footsteps of the Messiah when they ask, Where is the promise of his coming? 2Pe 3:3,4. The records of the Lord's dealings with the family of David, show us his dealings with his church, and with believers. Their afflictions and distresses may be grievous, but he will not finally cast them off. Self-deceivers abuse this doctrine, and others by a careless walk bring themselves into darkness and distress; yet let the true believer rely on it for encouragement in the path of duty, and in bearing the cross. The psalm ends with praise, even after this sad complaint. Those who give God thanks for what he has done, may give him thanks for what he will do. God will follow those with his mercies, who follow him with praises.
