Kommentar zu Divrej Hajamim I 28:10

for the Lord has chosen you to build a house for the Sanctuary not to build it for Him to dwell therein, for the heavens and the heavens of the heavens cannot contain Him, but for the Sanctuary, for the requirement of the Ark, which is called מִקְדָּשׁ, as it is written (Num. 10:21): “And the Kehathites, the bearers of the מִקְדָּשׁ traveled,” and that is the Ark. He did not choose you because you are more praiseworthy than other men, but for His sake and for the sake of His mercies; therefore be strong and do it.
