'Ill treatment' in the Bible

And so God has fulfilled what He foretold by the mouth of all the prophets, that His Christ (Messiah, Anointed) would suffer.

Because he saw one of them being mistreated, he defended and avenged the man who was suffering ill-treatment by striking down the Egyptian.

I have surely seen the ill treatment of my people which is in Egypt, and I have heard their groan, and have come down to take them out of it; and now, come, I will send thee to Egypt.
