'Souls' in the Bible

But we are not among those who shrink back to destruction, but among those who have faith to the preservation of [our] souls.

For consider the one who endured such hostility by sinners against himself, so that you will not grow weary in your souls [and] give up.

Obey your leaders and submit [to them], for they keep watch over your souls as those who will give an account, so that they can do this with joy and not [with] groaning, for this [would be] unprofitable for you.
