Following are a number of back-translations as well as a sample translation for translators of 2 Chronicles 29:31:

• Kupsabiny: “Hezekiah told all the people, ‘You have cleansed yourselves with respect to God. So, come forward and bring to the House of God the sacrifices and the things you have brought to give thanks to God.’ Then, those people arranged the things that were to be sacrificed and their things that were to be given to God to give thanks. All the people who had dedicated themselves to give animals for whole burnt sacrifices brought (them) also.” (Source: Kupsabiny Back Translation)
• Newari: “Hezekiah spoke to his subjects like this, "You have now dedicated yourselves to the LORD. Come to the temple of the LORD bringing your sacrifices and thank-offering." So the people of the assembly brought [their] sacrifices and thank-offerings. And all who had the desire to give brought their own burnt offerings.” (Source: Newari Back Translation)
• Hiligaynon: “Then Hezekia said, ‘Now that you have dedicated yourselves to the LORD, [you (plur.)] bring offerings, including the offerings of thanksgiving to the temple of the LORD.’ So the assembly/people brought these offerings to the temple of the LORD. Willingly was their offering burnt offerings.” (Source: Hiligaynon Back Translation)
• English: “Then Hezekiah said, ‘You have now dedicated yourselves to Yahweh. So come close to the temple and bring animals to be sacrificed and other offerings to thank Yahweh for what he has done for you.’ And those who wanted to bring animals to be completely burned on the altar brought them.” (Source: Translation for Translators)
