To men God says:

Psalm 90:3-10:
3 You return man to dust and say, “Return, O children of man!”
4 For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night.
5 You sweep them away as with a flood; they are like a dream, like grass that is renewed in the morning:
6 in the morning it flourishes and is renewed; in the evening it fades and withers.
7 For we are brought to an end by your anger; by your wrath we are dismayed.
8 You have set our iniquities before you, our secret sins in the light of your presence.
9 For all our days pass away under your wrath; we bring our years to an end like a sigh.
10 The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away.

Psalm 102:24-26:
24 “O my God,” I say, “take me not away in the midst of my days- you whose years endure throughout all generations!”
25 Of old you laid the foundation of the earth, and the heavens are the work of your hands.
26 They will perish, but you will remain; they will all wear out like a garment. You will change them like a robe, and they will pass away,

And so it is written:

Ecclesiastes 1:2-4:
2 Vanity of vanities, says the Preacher, vanity of vanities! All is vanity.
3 What does man gain by all the toil at which he toils under the sun?
4 A generation goes, and a generation comes, but the earth remains forever.

But to the Son he says:
10 And, “You, Lord, laid the foundation of the earth in the beginning, and the heavens are the work of your hands;
11 they will perish, but you remain; they will all wear out like a garment,
12 like a robe you will roll them up, like a garment they will be changed. But you are the same, and your years will have no end.”
Hebrews 1
