1 Chronicles 28:20

And David said to Solomon his son. — The conclusion of the speech begun in 1 Chronicles 28:9, and interrupted by the transfer of the plans and designs (1 Chronicles 28:11).

Be strong and of good courage. — So 1 Chronicles 22:13. “And do” is added here, because the time for action is imminent.

Fear not... forsake thee. — From Deuteronomy 31:6; Deuteronomy 31:8. (See also Joshua 1:5.)

My God. — Recalling, in a single word, all his own wonderful experience of the Divine Helper.

Fail. — Drop, let go, and so dismiss, desert.

Until. — The word implies nothing about the time beyond the expressed limit. (Comp. εws, Matthew 1:25.)
