Unclean SEPULCHER- WHITE HYPOCRITE - Matthew 23:27 KJV [27] Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men's bones, and of all uncleanness.
Unprofitable SERVANTS- BONDSERVANTS- Luke 17:10 KJV [10] So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
The best title to pick is servants, but if you study Bible and world history (including the US) being a servant is undesirable. It's the meanest, lowest type of job during Jesus' times... (Philippians 2:5- 11)
