During the translation of the New Testament into Huixtán Tzotzil, translation consultant Marion Cowan found that questions where the answer is obvious, affirmative rhetorical questions, as well questions raising objections tended to cause confusion among the readers. So these are rendered as simple or emphatic statements.

Accordingly, Matthew 7:9-11 reads “If your son asks you for a tortilla to eat, not a stone you would give him. If he asks you for fish to eat, not a snake you would give him. You whose hearts are not good, know what good gifts you will give your children. Your father in heaven surpassingly knows what good gifts he will give to those who ask him.”
