Their line. — Heb., kav, a cord, used of a plummet line (Zechariah 1:16); a measuring cord (Jeremiah 31:39, where also same verb, gone forth). In Isaiah 28:10, the word is used ethically for a definition or law. But neither of these seems very appropriate here. The verse wants sound or voice, and words of this intention actually appear in the LXX., Vulg., Symmachus, Jerome, and the Syriac.
The use which St. Paul makes of these words (Romans 10:18) is as natural as striking. The march of truth has always been compared to the spread of light. But the allegorical interpretation based on the quotation, making the heavens a figure of the Church and the sun of the Gospel, loses the force and beauty of the Apostle’s application.

A tabernacle. — The tent-chamber into which the sun retired after his day’s journey, and from which he started in the morn, Aurora, or dawn (according to Grecian mythology) drawing back the curtains for his departure, was naturally a conception common to all nations. That the phenomena of sunset should engage the poet’s attention before those of sunrise was inevitable in a race who reckoned “the evening and the morning were the first day.” The LXX. and Vulg. completely spoil the picture by rendering “he hath pitched his tent in the sun.”
