The first written mention of grass is found in which book?

The first written mention of grass is found in the "Bible", to be specific the mention is made in the book of Genesis 1:11-12 where God is mentioning the creation of vegetation and said "let the earth bring forth the grass". Usually it is confused with the Quran, Holy Book of Islam.
Here is the quotation from the Bible:

"Genesis 1:11-12King James Version (KJV)

11 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.

12 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good."
