Charles Ellicott Commentary Isaiah 5:19

"that say, Let him make speed, let him hasten his work, that we may see it; and let the counsel of the Holy One of Israel draw nigh and come, that we may know it!" — Isaiah 5:19 (ASV)

That say, Let him make speed. —We have here, as in Isaiah 28:10 and Jeremiah 17:15, the very words of the wealthy scoffers of Judah. Such taunts are not peculiar to any age or country. We find them in the speech of Zedekiah (1 Kings 22:24) and in that of the mockers of 2 Peter 3:4.

In the name of Isaiah’s second son (Isaiah 8:3), we may probably find an answer to the taunt. The words “the counsel of the Holy One of Israel” were obviously emphasized with a sneer at the name on which Isaiah dwelt so constantly. (Compare to Isaiah 30:11.)
