The Danish Bibelen 2020 translates Ecclesiastes 11:1 as “Be generous to ungrateful people because you will receive your reward at some point.”
Martin Ehrensvärd, one of the translators explains: “The first text we worked on in 2013 was Ecclesiastes. We used it as a test case to find out how we would implement our principles. We agreed then that we couldn’t do anything about obscure texts such as the saying in Eccl. 11:1: ‘Cast thy bread upon the waters: for thou shalt find it after many days.’ It’s a proverb, known from other sources in antiquity, but we are not sure about the deeper meaning of it. But five years down line we decided, for better or worse, that we should also help the reader in such difficult cases, and so instead of saying anything about casting bread, we said: ‘Be generous to ungrateful people because you will receive your reward at some point.'” (Source: Ehrensvärd in HIPHIL Novum 8/2023, p. 81ff. )
