The Torah represents total reality. We do not live in total reality, we live in a subset of reality. Therefore the Torah has to be interpreted according to the subset of reality in which we live, in order to make it accessible to us.
So for example, Rb Dessler points out that the moral interpretations of the prohibition to serve avodah zarah changes as you track commentators through the ages, to be a response to the avodah zarah prevalent in their times.
In other words, what this means to say (as an answer to your question), is that regarding Avraham for example, it says
אלא מלמד שזימן הקדוש ברוך הוא לאברהם אבינו שתי כליותיו כשני חכמים, והיו מבינות אותו ויועצות אותו ומלמדות אותו חכמה כל הלילה.
"This teaches you that Hashem set Avraham's two kidneys to be like two wise men and they taught him wisdom and council and they would teach him wisdom the entire night."
I.e. just as Avraham learnt the Torah through the lens of his personality, so too the Torah commentators see new understanding in the words of the Torah through the lens of their personality, in the way that they must perforce seek understanding in order to survive and flourish in a Torah manner according to the challenges and world-mask of their age.
