I Chronicles 28:10 and 20

"'Consider now, for the Lord has chosen you to build a house for the sanctuary; be strong, and do it.'"

"And David said to his son Solomon, 'Be strong and of good courage, and do it; do not fear nor be dismayed, for the Lord God--my God--will be with you. He will not leave you nor forsake you, until you have finished all the work for the service of the house of the Lord.'"
