וַיֹּ֣אמֶר יְהוָ֔ה רָאֹ֥ה רָאִ֛יתִי אֶת־עֳנִ֥י עַמִּ֖י אֲשֶׁ֣ר בְּמִצְרָ֑יִם וְאֶת־צַעֲקָתָ֤ם שָׁמַ֙עְתִּי֙ מִפְּנֵ֣י נֹֽגְשָׂ֔יו כִּ֥י יָדַ֖עְתִּי אֶת־מַכְאֹבָֽיו׃
Rashi on Exodus
כי 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.
Ramban on Exodus
AND THE ETERNAL SAID. Scripture mentions Him in the attribute of mercy since it is in connection with His compassion for the people [in bondage], even though the entire chapter mentions Him by the name of Elokim (G-d), [a name signifying the attribute of justice].
Rashbam on Exodus
ואת צעקתם שמעתי מפני נוגשיו, their outcry which was prompted because the taskmasters are constantly harassing them, I have heard.
