Judgment also will I lay to the line, &c. I will execute just judgment, as it were by a line and plummet annexed to it; that is, with exactness and care. I will severely punish and utterly destroy all who reject that stone. For the line and plummet, or the plumb-line, was not only used in erecting buildings, but also in pulling them down; those parts of the building being thus marked out which were to be demolished. And the hail shall sweep away the refuge of lies, &c. My judgments (which in the Scriptures are compared to a storm of hail or rain) shall discover the vanity of all your crafty and wicked devices, and shall sweep you away with the besom of destruction in spite of them.
