1 Corinthians 7:37

JMNT(i) 37 Now [he] who has been standing firm and is now settled in the seat of his heart – presently having no necessity (continuing to hold no compulsion) but holds authority concerning (or: has a right pertaining to) his own will and has decided this in his own heart – to continue keeping watch over and guarding his virgin [daughter; fianc'e9e; or, perhaps: his own virginity], will be doing beautifully (finely; ideally).
