The table below presents presents two contradictory verses. Both verses talk about the prophetic speech of God to Moses. The underlined words highlight the contradiction. One verse says God spoke in the voice, that is, the same thunderous, trumpet-like voice by which God spoke at Sinai, while the other verse says God only spoke to Moses; Aaron could not hear the voice. Which is it? Was the voice thunderous and loud? If so why couldn't Aaron hear it? Perhaps it was a soft voice? Rashi simply resolves this using the 2 Aspects method: God's voice spoke within Moses. Since He did not speak externally Aaron could not hear it. However the voice within was thunderous and loud.

Summary	Verse / Source	Text of verse / Source
God's voice is thunderous and loud	Nu07-69, Ex19-19,	#####
Only Moses heard God's voice, not Aaron	Nu07-69	And when Moses went into the tent of meeting that He might speak with him, then he heard the Voice speaking only to him from above the ark-cover that was upon the ark of the testimony, from between the two cherubim; and He spok
Resolution:	2 Aspects:	God's voice spoke within Moses (Nu12-06) Since He did not speak externally Aaron could not hear it. However the voice within was thunderous and loud.

Advanced Rashi: This is a peach of Rashi. We have not treated it completely above. A proper analysis would require use of 3 Rashi rules applied 5 times. In fact the original source of this Rashi is not on this verse but rather this Rashi is almost a verbatim citation from the Sifrah on Lv01-01. Here are the Rashi comments which fully justify this Rashi:
• Grammar: The article the indicates something well known.
• Reference: Hence when Nu07-69 refers to the voice that Moses heard it must be referring to some well known voice, namely, the voice of the revelation as accounted in Ex19-19. Note that additionally the Sifrah also cites Ps29 and Ps93 both of which explicitly deal with the magnitude of the voice.
• Grammar: The verb speak is normally accompanied by the pronoun in: You speak to someone in a certain place. However Lv01-01 uses the very rare construction God spoke to Moses from the Temple. The Sifray interprets this to mean that the voice never left the Temple (and hence was inaudible outside). Rather than get involved in defending this ##### #####
• Contradiction: Finally we have used the contradiction method as indicated above.

We might also indicate the moral point of Rashi: Why is the verse emphasizing that the voice was loud but inaudible.
• The emphasis on inaudibility to others is to indicate that God's voice is not an external voice in the physical world.
• The emphasis on loudness is to indicate that prophecy is not a seance-like state where one hears inaudible voices that murmur and hint at things. Rather prophecy is loud and clear; the prophet is certain of the message received and uses his normal mental state to receive the message.

We still haven't completely explained this Rashi but have presented its basis and showed various rich aspects of it.
