The internal evidence cited from “Ecclesiastes” to support Solomon’s authorship agrees with his perspective as a ruler and a father. The first evidence is the name he gives himself in the book – Qoheleth, which means “Preacher”. The “Ecclesiastes” is the book of wisdom which represents Solomon’s “last words” on the subject of kingship and assembly to determine the next king (Ecclesiastes 1:1, 2 12; 7:27; 12:8-10). The second evidence is the problem of succession because Solomon doubts David’s wisdom. This concern of succession accords with the story of foolish Rehoboam in Bible (Ecclesiastes 2:18-21). And the third evidence reflects ironic references to the division of Israel and Solomon’s greatness was being consigned to the oblivion that he feared. This refers to the prophecy of the reign of Jeroboam whose name was byword for sin. The kings of divided kingdom of Israel “followed in the sin of Jeroboam the son of Nebat, who made Israel sin” and were consigned to the oblivion(Ecclesiastes 4:13-16).
