ייִדישער מחשבֿה אויף ישעיהו 8:3

(5) After all these instructions, Abraham is advised that all the blessings in store for him will be shared by his wife in equal measure; therefore, her name also is to be changed. Just as a prince's wife becomes a queen when her husband becomes king, so Abraham's change of status brought in its wake a similar change of status for his wife. Interestingly, changes of status of the wife do not automatically confer a higher status on the husband, since we do not find that the prophetess Hulda's husband became a prophet (Isaiah chapter 8).
