Charles Ellicott Commentary Isaiah 2:5

"O house of Jacob, come ye, and let us walk in the light of Jehovah." — Isaiah 2:5 (ASV)

O house of Jacob...—The ideal of the future has been brought before Israel; but it is still far off, and the people must learn repentance, must themselves walk in the light of the Lord, before they can be as light-bearers to other nations. (Compare to the lines of thought in Romans 11:11-15.)
