Verse 30: For even at this time, my whole frame doth tremble exceedingly while attempting to speak unto you; but the Lord God doth support me, and hath suffered me that I should speak unto you
This makes me think of various prophets and apostles that I have seen speak in conference. They are old and their bodies are frail. Sometimes they cannot stand. Sometimes they can barely speak. Yet there they are, speaking to us and sharing their wisdom, because they are supported by the Lord God.
