Philemon 1:19
I, Paul, write this with my own hand: I will repay it — I say nothing of your owing me even your own self — the autograph (idiai cheiri — own hand) authenticates the promise with solemnity; this is Paul's personal bond. The assertion I will repay (apotisō) commits Paul's resources to settle the debt. The parenthetical reminder that Philemon owes Paul his very self (kai seauton) reverses the debtor-creditor dynamic: Philemon was spiritually bankrupt until Paul's ministry restored him; Paul's assumption of Onesimus's debt is repayment of an unpayable debt.
