But the man who is strong in mind and purpose, who is not forced but has control over his desires, does well if he comes to the decision to keep her a virgin.

ἑδραῖος hedraios “firm”

For this cause, my dear brothers, be strong in purpose and unmoved, ever giving yourselves to the work of the Lord, because you are certain that your work is not without effect in the Lord.

ἑδραῖοι hedraioi “steadfast”

If you keep yourselves safely based in the faith, not moved from the hope of the good news which came to you, and which was given to every living being under heaven; of which I, Paul, was made a servant.
