Ibn Ezra on Genesis 18:12/אבן עזרא על בראשית י״ח:י״ב

אהיתה לי. כמו תהיה לי:
1SHALL I HAVE. Hayetah li means shall I have.16 literally means I had. I.E. explains that hayetah is to be taken as an imperfect even though it is a perfect.
בעדנה. כמו עדן וענג, וכן ויתעדנו (נחמי' ט כה), והטעם אחר שבלותי וזקנתי איך תתחדש לי עדן ועונג הנוער ועוד כי אדוני זקן,
2PLEASURE. The word ednah means pleasure and enjoyment. Va-yitaddenu (and luxuriated) in and luxuriated (va-yitaddenu) in Thy great goodness (Neh. 9:25) is similar. The meaning of our verse is: How can the enjoyment and pleasure of youth be renewed in me, seeing that I have waxed old and aged and my husband, too, is old.
גוטעם בקרבה בנפשה והשם גלה סודה למלאך:
3[WITHIN HERSELF.] In her mind. God revealed Sarah’s inner thoughts to the angel.
