18 They have not come to know,+ nor do they understand,+ because their eyes have been besmeared so as not to see,+ their heart so as to have no insight.+

22 For my people is foolish.+ Of me they have not taken note.+ They are unwise sons; and they are not those having understanding.+ Wise they are for doing bad, but for doing good they actually have no knowledge.+

10 Many will cleanse themselves+ and whiten themselves+ and will be refined.+ And the wicked ones will certainly act wickedly,+ and no wicked ones at all will understand;+ but the ones having insight will understand.+

9 Who is wise, that he may understand these things?+ Discreet, that he may know them?+ For the ways of Jehovah are upright,+ and the righteous are the ones who will walk in them;+ but the transgressors are the ones who will stumble in them.+

11 there is no one that has any insight, there is no one that seeks for God.+

18 while they are in darkness mentally,+ and alienated+ from the life that belongs to God, because of the ignorance+ that is in them, because of the insensibility+ of their hearts.
