Isaiah 5:20

Those who call evil good and good evil are as good as dead, ¹  who turn darkness into light and light into darkness, who turn bitter into sweet and sweet into bitter. ² 

Pr 17:15; Mal 2:17; Mal 3:15; Mt 6:23; Mt 15:3-6; Mt 23:16-23; Lu 11:35; Lu 16:15; 2Ti 3:1-5; 2Pe 2:1,18,19

² sn In this verse the prophet denounces the perversion of moral standards. Darkness and bitterness are metaphors for evil; light and sweetness symbolize uprightness.
