King Solomon, the son of David, is the primary author of these proverbs. Other authors include Agur son of Jakeh (chapter 30) and King Lemuel (31:1-9). Neither of these men are mentioned elsewhere in the Bible. Lemuel's sayings contain several Aramaic rather than Hebrew spellings that point to a non-Israelite background. The proverbs in chapters 25-29 (see 25:1) were copied and compiled by the men of Hezekiah, one of the righteous kings of the southern kingdom of Judah.
