Below is the meaning of what "pine" may refer to as in the Gopher wood from which God told Noah to build the ark.
 
Also the "eight" reminds me of the 8 saved people in the ark.
 
 
..........In the Bible's book of Genesis we read that God told Noah to build an ark (a huge box-shaped vessel) of “gopher wood”. God said: “Make thee an ark of gopher wood …” (Genesis 6:14).
 
Gopher wood is mentioned only once in the Bible, and its identification has been the subject of great speculation. The meaning of the Hebrew word gopher is obscure. The sixteenth century Geneva Bible translated it as “pine-trees.” Rather than risk a wrong translation, the translators of the King James Version of the Bible (1611) simply kept the original Hebrew word and called it gopher wood.
