Charles Spurgeon Commentary 1 Chronicles 28:20

"And David said to Solomon his son, Be strong and of good courage, and do it: fear not, nor be dismayed; for Jehovah God, even my God, is with thee; he will not fail thee, nor forsake thee, until all the work for the service of the house of Jehovah be finished." — 1 Chronicles 28:20 (ASV)

He will not fail you, nor forsake you, until you have finished all the work for the service of the house of the LORD.

Therefore, be of good courage, you that are working for God, for he will not fail you, nor forsake you, until you have finished all the work for the service of the house of the Lord.

Fear not, nor be dismayed: for the LORD God, even my God, will be with you;

What a lovely touch that is! The LORD God, even my God, will be with you.
