1 Chronicles 28:18-20

Young's Literal Translation

¹⁸ and for the altar of perfume refined gold by weight, and for the pattern of the chariot of the cherubs of gold -- spreading and covering over the ark of the covenant of Jehovah.

¹⁹ The whole [is] in writing from the hand of Jehovah, `He caused me to understand all the work of the pattern,' [said David.]

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.
