1 Kings 4:29

Solomon's wisdom was more his glory than his wealth, and here we have a general account of it. I. The fountain of his wisdom: God gave it him, Kg1 4:29. He owns it himself. Pro 2:6, The Lord giveth wisdom. He gives the powers of reason (Job 38:36), preserves and improves them. The ordinary advances of them are owing to his providence, the sanctification of them to his grace, and this extraordinary pitch at which they arrived in Solomon to a special grant of his favour to him in answer to prayer. II. The fulness of it: He had wisdom and understanding, exceeding much, great knowledge of distant countries and the histories of former times, a quickness of thought, strength of memory, and clearness of judgment, such as never any man had. It is called largeness of heart; for the heart is often put for the intellectual powers. He had a vast compass of knowledge, could take things entire, and had an admirable faculty of laying things together. Some, by his largeness of heart, understand his courage and boldness, and that great assurance with which he delivered his dictates and determinations. Or it may be meant of his disposition to do good with his knowledge. He was very free and communicative, had the gift of utterance as well as wisdom, was as free of his learning as he was of his meat, and grudged neither to any that were about him.

HIS WISDOM. (Kg1 4:29-34) God gave Solomon wisdom and understanding exceeding much, and largeness of heart--that is, high powers of mind, great capacity for receieving, as well as aptitude for communicating knowledge.
