Ah! an introductory interjection, making way for his excuse in a way of grief and complaint, endeavouring with all reverence to clear himself of undertaking such a work rashly, it being properly the sigh of one that hath too great a weight upon his shoulders. I cannot speak; not dumb, as Zacharias, Luke 1:20,22, nor stammering, as Moses, Exodus 4:10,14; but not with that becoming gravity and commanding majesty as is suitable to a prophet; he modestly excuseth himself, from a consideration of the weight of the work, and the tenderness of his age, as in the next expression. I am a child; either,
1. In years, and so not ripe or apt for the declaring of great things, and that to princes and nobles. Or,
2. In experience, being altogether unskilful in such affairs, not having been used to prophesy, and therefore in neither respect likely to be much regarded.
