119Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth; walk in the ways of your heart and the sight of your eyes. But know that for all these things God will bring you into judgment.10Remove vexation from your mind, and put away pain from your body; for youth and the dawn of life are vanity.121Remember also your Creator in the days of your youth, before the evil days come, and the years draw nigh, when you will say, "I have no pleasure in them";2before the sun and the light and the moon and the stars are darkened and the clouds return after the rain;3in the day when the keepers of the house tremble, and the strong men are bent, and the grinders cease because they are few, and those that look through the windows are dimmed,4and the doors on the street are shut; when the sound of the grinding is low, and one rises up at the voice of a bird, and all the daughters of song are brought low;5they are afraid also of what is high, and terrors are in the way; the almond tree blossoms, the grasshopper drags itself along and desire fails; because man goes to his eternal home, and the mourners go about the streets;6before the silver cord is snapped, or the golden bowl is broken, or the pitcher is broken at the fountain, or the wheel broken at the cistern,7and the dust returns to the earth as it was, and the spirit returns to God who gave it.8Vanity of vanities, says the Preacher; all is vanity.
Psalms 90:3-6, 12-14, 17
3Thou turnest man back to the dust, and sayest, "Turn back, O children of men!" 4For a thousand years in thy sight are but as yesterday when it is past, or as a watch in the night. 5Thou dost sweep men away; they are like a dream, like grass which is renewed in the morning: 6in the morning it flourishes and is renewed; in the evening it fades and withers. 12So teach us to number our days that we may get a heart of wisdom. 13Return, O LORD! How long? Have pity on thy servants! 14Satisfy us in the morning with thy steadfast love, that we may rejoice and be glad all our days. 17Let the favor of the Lord our God be upon us, and establish thou the work of our hands upon us, yea, the work of our hands establish thou it.
43And all were astonished at the majesty of God. But while they were all marveling at everything he did, he said to his disciples, 44"Let these words sink into your ears; for the Son of man is to be delivered into the hands of men." 45But they did not understand this saying, and it was concealed from them, that they should not perceive it; and they were afraid to ask him about this saying.
