'Slave' in the Bible

Then she spoke to him with these words, “The Hebrew slave, whom you brought to us, came in to me to make sport of me;

Now when his master heard the words of his wife, which she spoke to him, saying, “This is what your slave did to me,” his anger burned.

So he said, “Now let it also be according to your words; he with whom it is found shall be my slave, and the rest of you shall be innocent.”

But he said, “Far be it from me to do this. The man in whose possession the cup has been found, he shall be my slave; but as for you, go up in peace to your father.”

Now, therefore, please let your servant remain instead of the lad a slave to my lord, and let the lad go up with his brothers.

“When he saw that a resting place was goodAnd that the land was pleasant,He bowed his shoulder to bear burdens,And became a slave at forced labor.
