The aim of this study is to organize the speech ideology of Ben Sira, a wisdom teacher and the first of the category of the scribes. To achieve this, both the analytical and synthetic methods are employed. The study reveals Ben Sira's emphasis on the dianoetic and dynamic aspects of speech. It highlights the recommendation of silence in wait for Kairos(propitious time) for effective speech. Ben Sira's indication that God is the architect of man's speech faculty forms the basis of a theological dimension of human speech. God's continued role in human speech affirms the possibility of Wisdom Theology of which the theology of human speech is an aspect.
