Haggai 1:13

In the second year of Darius the king, on the first day of the sixth month, the word of Yahweh came by the hand of Haggai the prophet to Zerubbabel the son of Shealtiel, governor of Judah, and to Joshua the son of Jehozadak, the high priest, saying,

“For the lips of a priest should keep knowledge, and men should seek instruction from his mouth; for he is the messenger of Yahweh of hosts.

“Behold, I am going to send My messenger, and he will prepare the way before Me. And the Lord, whom you seek, will suddenly come to His temple; and the messenger of the covenant, in whom you delight, behold, He is coming,” says Yahweh of hosts.
