1 Chronicles 28:20-21

Young's Literal Translation

²⁰ And David saith to Solomon his son, `Be strong, and courageous, and do; do not fear nor be affrighted, for Jehovah God, my God, [is] with thee; He doth not fail thee, nor forsake thee, unto the completion of all the work of the service of the house of Jehovah.

²¹ `And lo, courses of the priests and of the Levites [are] for all the service of the house of God; and with thee in all work [is] every willing one with wisdom, for every service; and the heads and all the people [are] according to all thy words.'
