Psalm 90:3-17 and Ecclesiastes 11:9-12:8

Psalm 90:3-17
3 And, lest man be turned aside in humiliation, you have said: Be converted, O sons of men.
4 For a thousand years before your eyes are like the days of yesterday, which have passed by, and they are like a watch of the night,
5 which was held for nothing: so their years shall be.
6 In the morning, he may pass away like grass; in the morning, he may flower and pass away. In the evening, he will fall, and harden, and become dry.
7 For, at your wrath, we have withered away, and we have been disturbed by your fury.
8 You have placed our iniquities in your sight, our age in the illumination of your countenance.
9 For all our days have faded away, and at your wrath, we have fainted. Our years will be considered to be like a spider's web.
10 The days of our years in them are seventy years. But in the powerful, they are eighty years, and more of these are with hardship and sorrow. For mildness has overwhelmed us, and we shall be corrected.
11 Who knows the power of your wrath? And, before fear, can your wrath
12 be numbered? So make known your right hand, along with men learned in heart, in wisdom.
13 Return, O Lord, how long? And may you be persuaded on behalf of your servants.
14 We were filled in the morning with your mercy, and we exulted and delighted all our days.
15 We have been rejoicing, because of the days in which you humbled us, because of the years in which we saw evils.
16 Look down upon your servants and upon their works, and direct their sons.
17 And may the splendor of the Lord our God be upon us. And so, direct the works of our hands over us; direct even the work of our hands.
Ecclesiastes 11:9-12:8
9 So then, rejoice, O young man, in your youth, and let your heart remain in what is good during the days of your youth. And walk in the ways of your heart, and with the perception of your eyes. And know that, concerning all these things, God will bring you to judgment.
10 Remove anger from your heart, and set aside evil from your flesh. For youth and pleasure are empty.
1 Remember your Creator in the days of your youth, before the time of affliction arrives and the years draw near, about which you will say, "These do not please me."
2 Before the sun, and the light, and the moon, and the stars are darkened and the clouds return after the rain,
3 when the guardians of the house will tremble, and the strongest men will waver, and those who grind grain will be idle, except for a small number, and those who look through the keyholes will be darkened.
4 And they will close the doors to the street, when the voice of he who grinds the grain will be humbled, and they will be disturbed at the sound of a flying thing, and all the daughters of song shall become deaf.
5 Likewise, they will fear the things above them, and they will dread the way. The almond tree will flourish; the locust will be fattened; and the caper plant will scattered, because man shall go into the house of his eternity, and the mourners shall wander around in the street.
6 Before the silver cord is broken, and the golden band pulls away, and the pitcher is crushed over the fountain, and the wheel is broken above the cistern,
7 and the dust returns to its earth, from which it was, and the spirit returns to God, who granted it.
8 Vanity of vanities, said Ecclesiastes, and all is vanity!
