'Working' in the Bible

For the hand of the Lord was against them, working their destruction, till all were dead.

If your brother, the son of your mother, or your son or your daughter or the wife of your heart, or the friend who is as dear to you as your life, working on you secretly says to you, Let us go and give worship to other gods, strange to you and to your fathers;

Let it not seem hard to you that you have to send him away free; for he has been working for you for six years, which is twice the regular time for a servant: and the blessing of the Lord your God will be on you in everything you do.
