| Geneva Study Bible So teach us to number our days, that we may apply our hearts unto {l} wisdom. (l) Which is by considering the shortness of our life, and by meditating the heavenly joys. Wesley's Notes 90:12 Teach us - To consider the shortness of life, and the certainty and speediness of death. That - That we may heartily devote ourselves to true wisdom. King James Translators' Notes apply: Heb. cause to come Jamieson-Fausset-Brown Bible Commentary 12. This he prays we may know or understand, so as properly to number or appreciate the shortness of our days, that we may be wise. Matthew Henry's Concise Commentary 90:12-17 Those who would learn true wisdom, must pray for Divine instruction, must beg to be taught by the Holy Spirit; and for comfort and joy in the returns of God's favour. They pray for the mercy of God, for they pretend not to plead any merit of their own. His favour would be a full fountain of future joys. It would be a sufficient balance to former griefs. Let the grace of God in us produce the light of good works. And let Divine consolations put gladness into our hearts, and a lustre upon our countenances. The work of our hands, establish thou it; and, in order to that, establish us in it. Instead of wasting our precious, fleeting days in pursuing fancies, which leave the possessors for ever poor, let us seek the forgiveness of sins, and an inheritance in heaven. Let us pray that the work of the Holy Spirit may appear in converting our hearts, and that the beauty of holiness may be seen in our conduct. |
