'Sinning' in the Bible

Say to the children of Israel, If any man's wife does wrong, sinning against him

And it will be that if the woman has become unclean, sinning against her husband, when she has taken the bitter water it will go into her body, causing disease of the stomach and wasting of the legs, and she will be a curse among her people.

The priest must then make atonement before the Lord on behalf of the person who acts in error sinning unintentionally, and when he makes atonement for him, he will be forgiven.

"But if you won't do so, look out! You will be sinning against the LORD. Be certain of this, that your sin will catch up to you!
