Almost the entirety of the chapter exhibits either pairs of related items or parallel clauses. In this verse, "sinful nation" parallels with "a people laden with iniquity," "offspring of evildoers" with "children who deal corruptly," and "they have forsaken the LORD" with "they have despised the Holy One of Israel." The clause "they are utterly estranged," however, isn't paired or paralleled with anything, and this lack of a complement emphasizes the meaning.
