Albert Barnes Commentary Exodus 3:7

"And Jehovah said, I have surely seen the affliction of my people that are in Egypt, and have heard their cry by reason of their taskmasters; for I know their sorrows;" — Exodus 3:7 (ASV)

Taskmasters - Oppressors. A different word from that in (Exodus 1:11).

I know - The expression implies personal feeling, tenderness, and compassion (Compare to Exodus 2:25 margin).
