590. Verse 9. If anyone hath an ear, let him hear, signifies that they should attend to this, who desire to attain wisdom. That by "having an ear to hear" is signified to perceive and obey, and also to attend, may be seen above (n. 87); that it also means those who desire to be wise, follows. Here it is said, "If anyone hath an ear let him hear," in order that they may attend to what goes before, and that otherwise they are not wise.
