of a donkey (derivative of ὄνος ‘donkey,’ 4.31) pertaining to a donkey In rendering MAT 18:6 it is important to avoid the impression that a donkey would turn the millstone in the same way that a person would. Sometimes a general causative expression may be used, for example, ‘a millstone that a donkey causes to go round (rotate),’ but it may actually be necessary to say ‘... which a donkey causes to go round (rotate) by pulling on a shaft.’ In fact, a marginal note may be necessary in order to avoid serious misunderstanding and to emphasize the fact that such a millstone was large and heavy.
