'Sinned' in the Bible

I will get up and go to my father, and I will say to him, “Father, I have sinned against heaven and in your sight.

And the son said to him, ‘Father, I have sinned against heaven and in your sight; I am no longer worthy to be called your son.’

Pay attention and always be on guard [looking out for one another]! If your brother sins and disregards God’s precepts, solemnly warn him; and if he repents and changes, forgive him.
