G0951–βεβαίωσις–bebaiōsis

So it is right for me to take thought for you all in this way, because I have you in my heart; for in my chains, and in my arguments before the judges in support of the good news, making clear that it is true, you all have your part with me in grace.

βεβαιώσει bebaiōsei “in confirmation”

For men at all times make their oaths by what is greater; and any argument is ended by the decision of the oath.

βεβαίωσιν bebaiōsin “confirmation”
