Following are a number of back-translations as well as a sample translation for translators of Isaiah 23:18:

• Kupsabiny: “But all their things that they get through trade shall belong to God. those things shall not be stored to pile up, but they shall be given to the people who pray to God and buy food and the clothes they need.” (Source: Kupsabiny Back Translation)
• Newari: “Her profit and what she earns, however, will be kept separate for the LORD. The wealth that she earns will not be gathered. The profit that comes from her business will be for the LORD’s people, for as much food as they need to eat and for nice clothing to wear.” (Source: Newari Back Translation)
• Hiligaynon: “But at the end, what she will-gain will- not -be-hidden but-rather she will-offer to the LORD in-order to buy plenty of food and fine/good kind of clothes for the people who serve the LORD.” (Source: Hiligaynon Back Translation)
• English: “But their profits will be given to Yahweh.
  The merchants will not hoard their money;
  instead, they will give it to Yahweh’s priests
  in order that they can buy food and nice clothes.” (Source: Translation for Translators)
