Sforno on Exodus 9:19/ספורנו על שמות ט׳:י״ט

1ועתה שלח העז את מקנך, in order that also the servants supervising the cattle would escape the hail together with their herds.. If G’d cared about the beasts, He most certainly cared about the human beings, as we know from Avot 3,18 חביב אדם כי נברא בצלם, “man is beloved as he (alone) has been created in G’d’s image.”
