This verse is in the form of a question and has two verbs: Will they not teach you, and tell you. They refers to the fathers in verse 8. Utter words out of their understanding: utter words translates “bring forth words.” This line parallels teach … and tell in the first line. The words which they bring forth are from “their heart” in Hebrew, which means from the depths of their understanding. The heart in Hebrew stands for the intelligence. The force of the negative question is to make a positive statement: “Indeed, they will teach you.” In translation it may be better to reduce the three verbs to two as in Good News Translation and others. In some languages it will be necessary to make explicit what they teach; for example, “They will teach you their wisdom” or “… what they have learned.”
