Following are a number of back-translations as well as a sample translation for translators of Ezekiel 31:15:

• Kupsabiny: “The God of power is saying: Mourning enveloped the water(s) on the day when the tree went down to the world of the dead. I stopped the streams and rivers so that no stream would flow there. And since that tree had died, I covered/enveloped the hills of Lebanon with darkness and made all trees in the forest dry up.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “The Lord GOD still continued to say, ‘On-the day that this tree will-be-brought now to the place of the dead-ones, I will-cover the deep springs as a sign of mourning. The water will- no longer -flow in the rivers, and there is no more abundant water. Because of this, Lebanon will-be-darkened and all the trees in the field will-wither.” (Source: Hiligaynon Back Translation)
• English: “This is what I, Yahweh the Lord, say: ‘When that great tree was cut down, it was as though the springs that watered it mourned for it, because I caused the plentiful water from the springs to dry up. I caused the mountains in Lebanon to become black, and all the trees there to wither.” (Source: Translation for Translators)
