'Another's' in the Bible

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

that is, that we may be mutually comforted by one another's faith, both yours and mine.

Who are you to pass judgment on another's servant? Before his own master he stands or falls. And he will stand, for the Lord is able to make him stand.

I do not mean yours but the other person's. For why is my freedom being judged by another's conscience?

Carry one another's burdens, and in this way you will fulfill the law of Christ.
