'Oppressed' in the Bible

Then the Lord said to Abram, "Know for certain that your descendants will be strangers in a foreign country. They will be enslaved and oppressed for four hundred years.

So Leah became pregnant and gave birth to a son. She named him Reuben, for she said, "The Lord has looked with pity on my oppressed condition. Surely my husband will love me now."

If the God of my father -- the God of Abraham, the one whom Isaac fears -- had not been with me, you would certainly have sent me away empty-handed! But God saw how I was oppressed and how hard I worked, and he rebuked you last night."
