Following are a number of back-translations as well as a sample translation for translators of 2 Kings 18:4:

• Kupsabiny: “He destroyed the altars which were on hills where idols were worshipped, and then he tore down the pillars. Then he cut the idol which was like Asherah to fall down. This king also broke the snake made from bronze which Moses made. He did like that because the people of Israel had started a habit of burning sacrifices to that snake and had given it the name of Nehushtan to be similar to other things that were being worshipped.” (Source: Kupsabiny Back Translation)
• Newari: “He removed the places to do puja, he broke to pieces the sacred stones pillars, he cut down the poles of the goddess Ashera. He broke to pieces the bronze serpent that Moses had made, for ’till that time the Israelites had been burning incense for it. They called it Nehushtan.” (Source: Newari Back Translation)
• Hiligaynon: “He caused-to-be-destroyed the places-of-worship in the high places, caused- the remembrance stones -to-be-smashed, and caused-to-be-cut-down the post/[lit. thing-like-pillar] which symbolizes the goddess Ashera. He also caused-to-be-smashed the bronze snake that Moises had-made, for up-to that time the Israelinhon worshipped it by burning incense. This bronze snake was called Nehushtan.” (Source: Hiligaynon Back Translation)
• English: “He destroyed the places where people worshiped Yahweh on the tops of hills, and he broke into pieces the stone pillars for worshiping the goddess Asherah. He also broke into pieces the bronze replica/statue of a snake that Moses had made. He did that because the people had named it Nehushtan, and they were burning incense in front of it to honor it.” (Source: Translation for Translators)
