2 Esdras 5:49-56

49 For as an infant does not bring forth, and a woman who has become old does not bring forth any longer, so I have made the same rule for the world that I created."
50 Then I inquired and said, "Since you have now given me the opportunity, let me speak before you. Is our mother, of whom you have told me, still young? Or is she now approaching old age?"
51 He replied to me, "Ask a woman who bears children, and she will tell you.
52 Say to her, "Why are those whom you have borne recently not like those whom you bore before, but smaller in stature?'
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 that already is aging and passing the strength of youth."
56 I said, "I implore you, O Lord, if I have found favor in your sight, show your servant through whom you will visit your creation."
