They still in heart and even in deed (comp. Isaiah 57:4-6, Isaiah 57:11, and Isaiah 65:3, as showing the habits of the exiles) clung to the old idolatries. The question for them was whether they would continue to walk in the ways of their fathers.
If so, it was true of them, as of the elders, that the Lent to whom they came would not be inquired of by them.
