'Sin' in the Bible

That Thou inquirest for mine iniquity, And for my sin seekest?

How many iniquities and sins have I? My transgression and my sin let me know.

But now, my steps Thou numberest, Thou dost not watch over my sin.

Yea, I have not suffered my mouth to sin, To ask with an oath his life.

For he doth add to his sin, Transgression among us he vomiteth, And multiplieth his sayings to God.

For thou sayest, 'What doth it profit Thee! What do I profit from my sin?'
