2 Esdras 5:53-55

Revised Standard Version

⁵³ And she herself will answer you, ‘Those born in the strength of youth are different from those born during the time of old age, when the womb is failing.’ ⁵⁴ Therefore you also should consider that you and your contemporaries are smaller in stature than those who were before you, ⁵⁵ and those who come after you will be smaller than you, as born of a creation which already is aging and passing the strength of youth.”
