'Sin' in the Bible

Then when the illicit desire has conceived, it gives birth to sin; and when sin has run its course, it gives birth to death.

But if you show partiality [prejudice, favoritism], you are committing sin and are convicted by the Law as offenders.

So any person who knows what is right to do but does not do it, to him it is sin.

But above all, my fellow believers, do not swear, either by heaven or by earth or with any other oath; but let your yes be [a truthful] yes, and your no be [a truthful] no, so that you may not fall under judgment.
