Isaiah 58:9

The Lord would hear their prayers, and they would enjoy His presence (cf. Isaiah 58:1-3). Making self the focus of life, in contrast, results in darkness (cf. Isaiah 5:20; Isaiah 8:20; Isaiah 47:5; Isaiah 60:2), disease (cf. Isaiah 1:5), defeat (cf. Isaiah 1:7), and separation (cf. Isaiah 1:4). For these blessings to come, God’s people needed to stop oppressing others, and to stop mocking and showing contempt for others with wicked speech (cf. Isaiah 57:4; Isaiah 66:5). Notice the "if . . . then" constructions in Isaiah 58:9-10; Isaiah 58:13-14. It is possible that "the pointing of the finger" may refer to being critical of others who are not as socially sensitive as oneself. [Note: Motyer, p. 482.]
