1 Kings 4:31

But that the object of Christianity is that we should become wise can be proved from the ancient Jewish writings, which we also use, as well as from those that were composed after the time of Jesus and that are believed among the churches to be divine. Now, in the fiftieth psalm, David is described as saying in his prayer to God these words: "The unseen and secret things of your wisdom you have manifested to me." Solomon, too, because he asked for wisdom, received it; and if anyone were to peruse the Psalms, he would find the book filled with many maxims of wisdom; and the evidences of Solomon's wisdom may be seen in his treatises, which contain a great amount of wisdom expressed in few words, and in which you will find many praises of wisdom and encouragements towards obtaining it. So wise, moreover, was Solomon, that the queen of Sheba, having heard his name and the name of the Lord, came to try him with difficult questions and spoke to him all things, whatsoever were in her heart; and Solomon answered her all her questions. There was no question omitted by the king that he did not answer her. And the queen of Sheba saw all the wisdom of Solomon and the possessions that he had, and there was no more spirit in her. And she said to the king, "The report is true that I heard in my own land regarding you and your wisdom; and I did not believe them who told me, until I had come, and my eyes have seen it. And, lo, they did not tell me the half. You have added wisdom and possessions above all the report that I heard." It is also recorded of him that "God gave Solomon very great wisdom, discernment and breadth of understanding as vast as the sand on the seashore, so that Solomon's wisdom surpassed the wisdom of all the people of the east and all the wisdom of Egypt.

For he was wiser than all men,....

Thus great was Solomon, but our Lord Jesus was greater than he ( Matt. xii. 42 ), though he took upon him the form of a servant; for divinity, in its lowest humiliation, infinitely transcends royalty in its highest elevation. 1 So king Solomon was king over all Israel.

Heman-- (1Ch 15:17-19) --the chief of the temple musicians and the king's seers (1Ch 25:5); the other two are not known. the sons of Mahol--either another name for Zerah (1Ch 2:6); or taking it as a common noun, signifying a dance, a chorus, "the sons of Mahol" signify persons eminently skilled in poetry and music.

He was wiser than all men - He was wiser than any of those who were most celebrated in his time, among whom were the four after mentioned, viz., Ethan, Heman, Chalcol, and Darda. Ethan was probably the same as is mentioned in some of the Psalms, particularly Psa 89:1, title; and among the singers in 1Ch 6:42. There is a Heman mentioned in the title to Psa 88:1. In 1Ch 2:6 we have all the four names, but they are probably not the same persons, for they are there said to be the sons of Zerah, and he flourished long before Solomon’s time. Some suppose that בני מחול beney machol should be rendered masters of dancing or music, as מחול machol signifies not only a dance or choir, but also an instrument of music of the pipe kind. Perhaps a reference is here made to Solomon’s skill in music and poetry, as he is compared to persons who appear to have been eminent poets and musicians.
