Zechariah 4:6-10

6 Then he answered and spoke to me, saying, "This is the word of Yahweh to Zerubbabel, saying, 'Not by might, nor by power, but by my Spirit,' says Yahweh of Hosts.  7 Who are you, great mountain? Before Zerubbabel you are a plain; and he will bring out the capstone with shouts of 'Grace, grace, to it!'"

8 Moreover the word of Yahweh came to me, saying,  9 "The hands of Zerubbabel have laid the foundation of this house. His hands shall also finish it; and you will know that Yahweh of Hosts has sent me to you.  10 Indeed, who despises the day of small things? For these seven shall rejoice, and shall see the plumb line in the hand of Zerubbabel. These are the eyes of Yahweh, which run back and forth through the whole earth."
