For who hath despised the day of small things? for they shall rejoice, and shall see the plummet in the hand of Zerubbabel with those seven; they are the eyes of the LORD, which run to and fro through the whole earth. Who hath despised the day of small things? - The poverty, weakness, and unbefriended state of the Jews. It was said, "What do these feeble Jews?" "Will they build," etc.? No. But God will build by them, and perfect his building too.
And shall see the plummet in the hand of Zerubbabel - He is master builder under God, the grand architect.
Those seven - are the eyes of the Lord - Either referring to his particular and especial providence; or to those ministering spirits, whom he has employed in behalf of the Jews, to dispense the blessings of that providence. See 2 Chronicles 16:9 (note); Proverbs 15:3 (note); Zephaniah 3:9 (note).
