Rashi on Exodus 3:7/רש"י על שמות ג׳:ז׳

1כי ידעתי את מכאביו FOR I KNOW THEIR SORROWS — The verb has the same meaning as in (Exodus 2:25) “and God knew”, signifying as much as: for I have set my heart upon noticing and understanding their sorrows, and I have not hidden my eyes from their distress, nor have I stopped my ears against their cry.
