Then Zerubbabel son of Shealtiel and Joshua son of Jehozadak, the high priest, as well as all the remnant of the people, obeyed the voice of the LORD their God and the words of the prophet Haggai, because the LORD their God had sent him. So the people feared the LORD.
The Prophet here declares that his message had not been without fruit, for shortly after the whole people prepared themselves for the work. And he names both Zerubbabel and Joshua; for it behaved them to lead the way, and, as it were, to extend a hand to others. For, had there been no leaders, no one of the common people would have pointed out the way to the rest.
As an ear-ring of gold (says Solomon), and an ornament of fine gold, so amiable, so acceptable, in the sight of God and man, is a wise reprover upon an obedient ear, Pro 25:12. The prophet here was a wise but faithful reprover, in God's name, and he met with an obedient ear.
Commenting on Haggai 1:12-15
Then Zerubbabel the son of Shealtiel, and Joshua the son of Josedech the high priest,.... Here follows an account of the success of Haggai's prophecy; with what power and efficacy the word of the Lord by him was attended; how it at once reached and affected the hearts of princes and people, and brought them to obedience to the will of God.
