A wise and an understanding heart - Solomon’s wisdom seems to have been both moral and intellectual (see 1 Kings 4:29-34). But it was moral wisdom alone which he requested, and which was promised him. The terms translated “wise” and “understanding,” both denote practical wisdom. (See Genesis 41:33, Genesis 41:39; Deuteronomy 4:6; Proverbs 1:2, etc.)
Neither after thee shall any arise like unto thee - i. e. in the knowledge of what was in man, and in the wisdom to direct men’s goings, he was to be the wisest of “all” mere men. In such wisdom the world would know one only “greater than Solomon” Matthew 12:42; Luke 11:31.
