1 Corinthians 9:20-22

Young's Literal Translation

²⁰ and I became to the Jews as a Jew, that Jews I might gain; to those under law as under law, that those under law I might gain;

²¹ to those without law, as without law -- (not being without law to God, but within law to Christ) -- that I might gain those without law;

²² I became to the infirm as infirm, that the infirm I might gain; to all men I have become all things, that by all means I may save some.
