'Own' in the Bible

But let each one examine his own work, and then he will have a reason for boasting in himself alone, and not in someone else.

For each one will carry his own burden.

because the one who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit.

See with what large letters I am writing to you with my [own] hand.
