19 By your endurance you will gain your lives.

19 By your patient endurance gain your souls^D7408.

Darby Bible Notes

souls - Or 'possess your souls.' In the first sense, that of the text, it is the same thought as Matt. 24.13; Luke 17.33; Matt. 16.25; Luke 9.24, &c.. see Mark 13.13. For the second, the Greek certainly means 'possess,' as 'owners,' Acts 4.34. See 1Thess. 4.4, which evidently does not mean 'obtain a wife,' as alleged. There is the idea in the word of 'having by getting.' see Matt. 10.9; Luke 18.12. The idea is, 'they would have Messiah's deliverance,' and it is so worded as to allow that it would be a better deliverance to the killed, though some would win life here below.

KJV

19 “In your patience possess ye your souls.”
