Mark 4:13

Outside

Seeing See Not Perceive  βλέπωσιν μὴ ἴδωσιν

Hearing Hear Not Understand ἀκούωσιν μὴ συνιῶσιν

Is 6:9   שִׁמְע֤וּ שָׁמֹ֨ועַ֙ וְאַל־תָּבִ֔ינוּ וּרְא֥וּ רָאֹ֖ו וְאַל־תֵּדָֽעוּ

Is 6:10 הַשְׁמֵן֙ לֵב־הָעָ֣ם הַזֶּ֔ה וְאָזְנָ֥יו הַכְבֵּ֖ד וְעֵינָ֣יו הָשַׁ֑ע פֶּן־יִרְאֶ֨ה בְעֵינָ֜יו וּבְאָזְנָ֣יו יִשְׁמָ֗ע וּלְבָבֹ֥ו יָבִ֛ין וָשָׁ֖ב וְרָ֥פָא לֹֽו
