Oznayim la'Torah (citing the Midrash Rabah): Par'oh's heart became like a liver, inasmuch as Par'oh's heart was angry like a liver, it was devoid of understanding like a liver and it was full of blood (the blood of the Jewish babies in whose blood he bathed) like a liver. And what's more, it is joined to the Marah (the gall of the liver), symbolizing the bitterness of Yisrael that he caused.
