Following are a number of back-translations as well as a sample translation for translators of 2 Kings 17:21:

• Kupsabiny: “In the old/former (time) when God had removed Israel from the rulership of the house of David, the people of that country anointed Jeroboam son of Nebat to become their king. Jeroboam made the people of Israel to become lost until they no longer followed God. That led them to do amazing sin/evil!” (Source: Kupsabiny Back Translation)
• Newari: “After the LORD separated Israel from the house of David, the Israelites made Jeroboam son of Nebat king. Having caused Israel to be far from the LORD, Jeroboam caused them to commit great sin.” (Source: Newari Back Translation)
• Hiligaynon: “When the LORD separated Israel from the kingdom of David, those of-Israel made Jeroboam the child/(son) of Nebat their king. Jeroboam urged/enticed those of/from-Israel to turn-away from the LORD, and he encouraged/pushed them to do great/[lit. big] sin.” (Source: Hiligaynon Back Translation)
• English: “Earlier, when Yahweh allowed the people of Israel to separate/break away from the area that King David had estabished, they chose Jeroboam, the son of Nebat, to be their king. Then Jeroboam enticed the people of Israel to stop worshiping Yahweh and to worship idols instead. He led them to commit great sins.” (Source: Translation for Translators)
