Good comparison! The Ark was surrounded by waters just like the tongue is surrounded by waters!

Genesis 7:11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. Continuing with the temple imagery that I mentioned in the other post, the tongue can be seen as a firmament (curtain, wall) dividing between the waters above and below, just like in Day 2 of Creation. The waters below picture the netherworld (throat, pit) and the waters above are like a "heaven" (in Portuguese this upper part of the mouth is called "mouth's sky/heaven") with the head picturing God's abode. No wonder then that the Hebrew words for tongue and firmament share the same numerical value!
Lashon (Tongue) = 380 = Firmament (Raqiya)
Lashon is written Lamed + Shin Nun, which makes me think of the Staff (Lamed) between the Teeth (Shin). When we pronounce the letter L (Lamed), our tongues point upward to "heaven" just like the letter Lamed points upward to God.
LAMED. For ever, O LORD, thy word is settled in heaven. - Psa 119:89
