Yesaya 6:9
Konteks6:9 He said, “Go and tell these people:
‘Listen continually, but don’t understand!
Look continually, but don’t perceive!’
Markus 4:12
Konteks4:12 so that although they look they may look but not see,
and although they hear they may hear but not understand,
so they may not repent and be forgiven.” 1
[4:12] 1 sn A quotation from Isa 6:9-10. Thus parables both conceal or reveal depending on whether one is open to hearing what they teach.
