Divrey Hayamim Alef 28:20

And Dovid said to Sh'lomo bno, Chazak! Ve'emetz! (Be strong and take courage!) And do it; fear not, nor be discouraged; for HASHEM Elohim, even Elohai, will be with thee; He will not fail thee, nor forsake thee, until thou hast finished all the work for the Avodas Bais HASHEM.
