Following are a number of back-translations as well as a sample translation for translators of 1 Samuel 20:13:

• Kupsabiny: “I swear before you that if I know that my father wants to kill you and I don’t remind you to flee, God should kill me. Let God protect you as he protected my father.” (Source: Kupsabiny Back Translation)
• Newari: “But if my father thinks to harm you, if I do not send you off to escape in peace by reporting this to you, may the LORD kill me. May the LORD be with you like He has been with my father.” (Source: Newari Back Translation)
• Hiligaynon: “But if my father has an intention/plan of killing you (sing.), and I do- not -let- you (sing.) -know so-that you (sing.) can-flee, may the LORD punish me severely/[double emphasis marker]. Now, may the LORD be-with you (sing.) as he has-been-with my father.” (Source: Hiligaynon Back Translation)
• English: “But if he is planning to hurt/kill you, I will enable you to know that, and enable you to go away safely. I desire that Yahweh will punish me severely if I do not do that for you. I desire/hope that Yahweh will be with you and help you like he has helped my father.” (Source: Translation for Translators)
