Albert Barnes Commentary 2 Chronicles 1:7-12

"In that night did God appear unto Solomon, and said unto him, Ask what I shall give thee. And Solomon said unto God, Thou hast showed great lovingkindness unto David my father, and hast made me king in his stead. Now, O Jehovah God, let thy promise unto David my father be established; for thou hast made me king over a people like the dust of the earth in multitude. Give me now wisdom and knowledge, that I may go out and come in before this people; for who can judge this thy people, that is so great? And God said to Solomon, Because this was in thy heart, and thou hast not asked riches, wealth, or honor, nor the life of them that hate thee, neither yet hast asked long life; but hast asked wisdom and knowledge for thyself, that thou mayest judge my people, over whom I have made thee king: wisdom and knowledge is granted unto thee; and I will give thee riches, and wealth, and honor, such as none of the kings have had that have been before thee; neither shall there any after thee have the like." — 2 Chronicles 1:7-12 (ASV)

The verbal differences between this passage and the corresponding one in 1 Kings 3:5–14 are quite significant. They indicate a general truth: the goal of the sacred historians is to give a true account of the substance of what was said, not necessarily to provide every exact word that was spoken. The most important point omitted in Chronicles, but included in Kings, is the conditional promise of long life made to Solomon (1 Kings 3:14). Meanwhile, the main point absent from Kings, but recorded by this author, is Solomon's solemn appeal to God's promise to his father David (2 Chronicles 1:9), which he now called upon God to “establish,” or fulfill.

I will give you riches, and wealth, and honor. Notice that the writer says nothing about any promise of “long life” to Solomon, even though it was mentioned in 2 Chronicles 1:11 as one of the blessings he might have been expected to ask for. The reason for this omission seems to be the writer's desire to record only what is good about this great king. Long life was included in the promises made to him, but it was granted conditionally. Since Solomon did not fulfill the conditions, the promise did not take effect (see the note on 1 Kings 3:14).
