'Else's' in the Bible

And if you haven't been trustworthy with someone else's property, who will give you your own?

Who are you to criticize someone else's servant? He stands or falls before his own Lord and stand he will, because the Lord makes him stand.

My aim is to evangelize where Christ has not been named, so that I will not build on someone else’s foundation,

The spiritual person evaluates everything but is subject to no one else's evaluation.

I mean, of course, his conscience, not yours. For why should my freedom be determined by someone else's conscience?

so that we may proclaim the good news to the regions beyond you, not boasting about what has already been done in someone else’s area of ministry.
