Verse 45. - The days of his youth hast thou shortened. This does not seem to mean an actual cutting short by death (since the Davidical king has been spoken of as alive in vers. 38, 41, 43), but rather a cutting short of youthful energy and vigour, a premature senescence, such as may well have fallen upon Jehoiachin or Zedekiah. Thou hast covered him with shame; or, "heaped shame upon him" - "covered him up with shame." The phrase would suit Jehoiachin, who was kept in prison by Nebuchadnezzar, and in "prison garments" (2 Kings 25:29), for the space of thirty-five years.

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.The days of his youth hast thou shortened,.... His days of joy and pleasure; such as days of youth are, in opposition to the days of old age, which are evil, Ecclesiastes 11:9, these were shortened when his sorrows and sufferings came on, and God hid his face from him; and indeed he was a man of sorrows, and acquainted with grief all his days: the Vulgate Latin version renders it, "the days of his time"; and the Arabic version "the days of his years"; for he did not live out half the time of man's age, which is threescore years and ten, Psalm 90:10, he dying at the age of thirty three or four; but, notwithstanding this, he lives again, and lives for evermore; he has length of days for ever and ever, Psalm 21:4, though his days were in some sense shortened, yet in another sense they are and will be prolonged, even his own, and those of his spiritual seed, according to the promise of God, Isaiah 53:10,

thou hast covered him with shame; see Psalm 69:7, when his face was covered with shame and spitting, from which he hid it not, Isaiah 1:6, but now he is crowned with glory and honour; wherefore all these complaints, though true, are no objections to what is before said and swore to.
