Chasidut su Isaia 6:9

Those who were less capacious absorbed less, becoming endowed with the Holy Spirit [ruakh ha-kodesh], or simply servants of God (not as ones with dried out and darkened hearts and souls, but as lofty people with the flame of God lit inside). And, to our sorrow, there were also lesser ones, about whom it is said “[they] hear indeed but do not understand; see, indeed, but do not grasp; the heart of this people has become dulled…”²²⁵See Isaiah 6:9-10. In place of ‘the heart of this people has become dulled,’ JPS has ‘dull that people’s mind.’
