C. F. Keil and Franz Delitzsch on 2 Chronicles 9:25-28

2Ch 9:25-28 2Ch 9:25 does not correspond to the passage 1Ki 10:26, but in contents and language agrees with 1Ki 5:6, and 2Ch 9:26 with 1Ki 5:1. Only the general estimate of Solomon’s riches in gold and silver, in 2Ch 9:27, repeated from 2Ch 1:15, corresponds to 1Ki 10:27. Finally, in 2Ch 9:28 the whole description is rounded off; all that has already been said in 2Ch 1:16, 2Ch 1:17 as to the trade in horses with Egypt (1Ki 10:28-29) being drawn together into one general statement.
