When the Jews were told to go up into the Holy Land they feared the warnings of the spies and didn't go up and they rebelled against "the mouth (word)" of God (9:23), the gematria of "the mouth" is Na Nach Nachma Nachman MeUman [anyone interested in seeing the actual Hebrew words can find them on the Hebrew na-nach.net].
Later in the Parsha, there is a verse regarding the congregation of Korach, 'the land opened it's mouth', which also includes in it the numerical value of 'the mouth' - Na Nach Nachma Nachman MeUman. There is another amazing find in these four words, for they are an anagram containing in them the letters P'Tz'P'Tz'Y'H - the holy name mentioned in the Petek, the name of the angel in charge of the sounds of the Shofar on the New Years, in addition it has the letters Tuv Resh Tuv, which is how the holy books write Tikeya Teruah Tikeya - the names of a distinct sounding of the Shofar. There remains four letters: H'A' H'A'!!!!!
