Sforno on Genesis 32:13/ספורנו על בראשית ל״ב:י״ג

1ואתה אמרת היטב איטיב עמך, if what I am afraid of were to happen this would be the reverse of Your promise to me. How can I watch the destruction of my family?

2ושמתי את זרעך, even if only my children will be killed this will be the opposite of what You promised. It behooves You to let them survive for the sake of Your great name, even if I myself do not deserve to survive. We use this kind of argument in our prayers when we say (based on Jeremiah 14,7) אם עונינו ענו בנו עשה למען שמך, “if our sins testify against us, (save us) for the sake of Your name!”
