1 Corinthians 9:19

For though I be free from all men, yet have I made myself servant unto all, that I might gain the more.

For though I was free from all, I brought myself under bondage to all, that I might gain the more.

For though I was free from all `men,' I brought myself under bondage to all, that I might gain the more.

for being free from all men, to all men I made myself servant, that the more I might gain;

Though I am free of obligation to anyone, I make myself a slave to everyone, to win as many as possible.
