If you do that you shall get life that is long and live/stay in that land that God promised to you grandfathers Abraham, Isaac and Jacob that he would give to you.’” (Source: Kupsabiny Back Translation)

• Hiligaynon: “You (plur.) love the LORD your (plur.) God. You (plur.) obey him and remain in him, for he is your (plur.) life. If you (plur.) will-do this, you (plur.) will-live long there in the land that he has sworn to give to your (plur.) ancestors who were Abraham, Isaac and Jacob.’” (Source: Hiligaynon Back Translation)
• English: “Choose to love Yahweh our God, and to obey him , and to be faithful to/have a close relationship with him. If you do that, you and your descendants will live for a long time in the land that Yahweh solemnly promised to your ancestors Abraham, Isaac, and Jacob, that he would give to them.’” (Source: Translation for Translators)
