'Weapon' in the Bible

For sin, seizing its opportunity through the commandment, beguiled and completely deceived me, and using it as a weapon killed me [separating me from God].

Did that which is good [the Law], then become death to me? Certainly not! But sin, in order that it might be revealed as sin, was producing death in me by [using] this good thing [as a weapon], so that through the commandment sin would become exceedingly sinful.
