Following are a number of back-translations of John 15:13:

• Chol: «There is much love in the one who will give himself to die on behalf of his friends. There is no one who has more love than this.»
• Ojitlán Chinantec: «If one is willing to die for a friend, he has loved that one to completion.»
• Huehuetla Tepehua: «The biggest love is this, when a person gives up his life for a friend of his.»
• Shipibo-Conibo: «Only upon very really loving their friend can they want to die in his place.»
• Yanesha’: «There isn’t love which surpasses this: We let go of ourselves to die for our loved ones.» (Source for this and above: M. Larson / B. Moore in Notes on Translation February 1970, p. 1-125.)
• Uma: «If there is a person who gives his life so that his companion lives, his love is indeed big. There is no love greater than the love of a person who gives his life in order to help his companion.» (Source: Uma Back Translation)
• Yakan: «If a person submits to die because of his love for his friends, there is no human love greater than this.» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «If there is a person who allows himself to be killed in order to free his friends, this is a sign that his friends are very dear in his breath. There is no dearness which can equal this.» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «This is the largest love that a person is able-to-show, if he dies so that his friends may live.» (Source: Kankanaey Back Translation)

In Ogea the word for «love» is «die for someone,» echoing the content of this verse. (Source. Sandi Colburn in Hiolzhausen 1991, p. 22)
