This is a Greek word that is the equivalent to the modern English word "shit." Skubala is a rare word, used only in Philippians 3:8 in the New Testament. Dung, rubbish, refuse, and a loss are various inaccurate translations of the Greek word. No translation accurately translates this term to its modern English equivalence: "shit." The word means "excrement" either animal or human. It is a very strong word!
Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord, for whom I have suffered the loss of all things and count them but dung (shit: Paul's intended power if this word is neglected) , that I may win Christ.
