Judgment also will I lay to the line, and righteousness to the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place.
Judgment also will I lay to the line - the measuring- line of the plummet. Horsley translates, 'I will appoint judgment for the rule, and justice for the plummet.' As the cornerstone stands most perpendicular and exactly proportioned, so Yahweh, while holding out grace to believers in the Foundation stone, will judge the scoffers (Isaiah 28:15) according to the exact justice of the law (cf. James 2:13).
The hail - Divine judgments (Isaiah 30:30; Isaiah 32:19).
