'Another's' in the Bible

If you have not been faithful in that which is another's, who will give you that which is your own?

If I then, the Lord and the Teacher, have washed your feet, you also ought to wash one another's feet.

Who are you who judge another's servant? To his own lord he stands or falls. Yes, he will be made to stand, for God has power to make him stand.

yes, making it my aim to preach the Good News, not where Christ was already named, that I might not build on another's foundation.

Bear one another's burdens, and so fulfill the law of Christ.
