God having, as it were on his own behalf, shown how kind he had been, calls upon them to speak now, if they knew any thing of injury, either in breach of covenant or severity, that they can charge him with, that they have thus apostatized. See Poole on "Isaiah 1:18"; See Poole on "Isaiah 5:3": compare Micah 6:2-4. By this manner of speech his proceeding appears the more justifiable; he both makes their conviction the clearer, and the reproof the sharper. Walked after vanity, viz. idols, showing their folly in going from God to such vain things as idols are, Deuteronomy 32:21 1 Samuel 12:20,21; and see on Isaiah 41:29; the abstract for the concrete, Ecclesiastes 1:2. Become vain, viz. in following their imaginations; fools, Romans 1:21,22, as senseless as the stocks and stones that they made their idols of, Psalms 115:8; and herein they are said to go far from God, and choose their delusions, Jonah 2:8.
