1 Chronicles 22:13

Then shalt thou prosper. — The verse makes it quite clear that obedience was an indispensable condition to the full realisation of the promise. (Comp. 1 Chronicles 22:10 with the actual after-course of history.) Yet the word of the Lord does not return unto Him void; and if the earthly dynasty of David came to an end through disobedience, in due time was born an heir of David and Solomon, who is at this day the Lord of a spiritual dominion which will endure throughout the ages.

If thou takest heed to fulfil. — Literally, if thou keep to do the statutes and judgments: language which is obviously a reminiscence of Deuteronomy. (Comp. Deuteronomy 7:11; Deuteronomy 11:32.)

Be strong, and of good courage. — Or, Be stout and staunch! a frequent phrase in Joshua (1 Chronicles 1:7, &c.).

Dread not, nor be dismayed. — So Deuteronomy 1:21; Deuteronomy 31:8; Joshua 1:9.

Dismayed. — Broken, i.e., in spirit: metu fractus. (Comp. “Solomon my son is young and timid,” 1 Chronicles 22:5.)
