1. It was supposed that the people would ask the meaning of this sign, or at least they should (v. 9): "Hath not the house of Israel said unto thee, What doest thou? Yes, I know they have. Though they are a rebellious house, yet they are inquisitive concerning the mind of God," as those (Isa. lviii. 2) who sought God daily. Therefore the prophet must do such a strange uncouth thing, that they might enquire what it meant; and then, it may be hoped, people will take notice of what is told them, and profit by it, when it comes to them in answer to their enquiries. But some understand it as an intimation that they had not made any such enquiries: "Hath not this rebellious house so much as asked thee, What doest thou? No; they take no notice of it; but tell them the meaning of it, though they do not ask." Note, When God sends to us by his ministers he observes what entertainment we give to the messages he sends us; he hearkens and hears what we say to them, and what enquiries we make upon them, and is much displeased if we pass them by without taking any notice of them. When we have heard the word we should apply to our ministers for further instruction; and then we shall know if we thus follow on to know.
