'Perpetual' in the Bible

Do not go on offering members of your body to sin as instruments of wickedness. But offer yourselves to God [in a decisive act] as those alive [raised] from the dead [to a new life], and your members [all of your abilities—sanctified, set apart] as instruments of righteousness [yielded] to God.

Before this faith came, we Jews were perpetual prisoners under the Law, living under restraints and limitations in preparation for the faith which was soon to be revealed.

and perpetual friction between men who are corrupted in mind and deprived of the truth, who think that godliness is a source of profit [a lucrative, money-making business—withdraw from them].

this Priest, on the contrary, after offering for sins a single sacrifice of perpetual efficacy, took His seat at God's right hand,

just as Sodom and Gomorrah and the adjacent cities, since they in the same way as these angels indulged in gross immoral freedom and unnatural vice and sensual perversity. They are exhibited [in plain sight] as an example in undergoing the punishment of everlasting fire.
