Following are a number of back-translations as well as a sample translation for translators of 2 Samuel 21:2:

• Kupsabiny: “So, that king called the people of Gibeon. They did not belong to Israel, but they were Amorites. The Israelites had sworn that they would not do anything to those people, but Saul fought them because, he thought that those people might one time turn against them.” (Source: Kupsabiny Back Translation)
• Newari: “(The Gibeonites were not of the tribes [of] Israel. They were the ones spared of the Amorite clan. The Israelites had sworn an oath saying that they would spare them. In spite of that, Saul in his enthusiasm for Israel and Judah tried to destroy them.) So King David called the Gibeonites” (Source: Newari Back Translation)
• Hiligaynon: “These Gibeonhon were not Israelinhon but-rather they were the remaining-ones who were alive among the Amornon. The Israelinhon had-promised that they will- not -kill them, but Saul tried to destroy them because of his great concern to/for Israel and Juda.
  David summoned/called-for the Gibeonhon” (Source: Hiligaynon Back Translation)
• English: “The people of Gibeon were not Israelis; they were a small group of the Amor people-group whom the Israelis had solemnly promised to protect. But Saul had tried to kill all of them because he was very zealous/wanted very much to enable the people of Judah and Israel to be the only ones living in that land. So the king summoned the leaders of Gibeon” (Source: Translation for Translators)
