'Sin' in the Bible

having risen, I will go on unto my father, and will say to him, Father, I did sin -- to the heaven, and before thee,

and the son said to him, Father, I did sin -- to the heaven, and before thee, and no more am I worthy to be called thy son.

'Take heed to yourselves, and, if thy brother may sin in regard to thee, rebuke him, and if he may reform, forgive him,

and if seven times in the day he may sin against thee, and seven times in the day may turn back to thee, saying, I reform; thou shalt forgive him.'
