Zechariah 4:6-7

Then he answered and spake unto me, saying, This is the word of Jehovah unto Zerubbabel, saying, Not by might, nor by power, but by my Spirit, saith Jehovah of hosts. Who art thou, O great mountain? before Zerubbabel thou shalt become a plain; and he shall bring forth the top stone with shoutings of Grace, grace, unto it.
