590. [verse 9] 'If anyone has an ear, let him hear' signifies that those who wish to be wise pay attention to these things. That by 'to have an ear to hear' is signified to perceive and obey, and also to pay attention, may be seen above (n. 87). It follows that it also means those who wish to be wise. Here it is said, 'if anyone has an ear, let him hear', in order that they may pay attention to the foregoing things, and that otherwise they are not wise.
