Having just said (in Pasuk 7) that He has heard Yisrael's cries, why does Hashem say here that their cries have reached him?
Ramban: Since the Egyptians had gone too far in their oppression of Yisrael, their cries had reached the Heavenly Throne. Consequently, Hashem would no longer turn a blind eye to what Pharaoh was doing but would proceed to take action.
Seforno: He meant that had accepted their prayers, because they were genuine. 1
What is Hashem adding with the last phrase ("and I have also seen the oppression ... ")?
