The Greek word for "frankincense" (λίβανος, "libanos") means "frankincense-tree, Boswellia Carterii; the gum of the tree λίβανος, used to burn at sacrifices."
Wikipedia opines, "The name of frankincense in Koine Greek (the language of the New Testament)…is cognate with the name of Lebanon (λίβανος, 'libanos'); the same can be said with regard to Arabic, Phoenician, Hebrew, and Vulgar Latin. This is postulated to be because they both derive from the word for 'white' and that the spice route went via Mount Lebanon."
Leviticus 2:1–2
When anyone brings a grain offering as an offering to the LORD, his offering shall be of fine flour. He shall pour oil on it and put frankincense on it and bring it to Aaron's sons the priests. And he shall take from it a handful of the fine flour and oil, with all of its frankincense, and the priest shall burn this as its memorial portion on the altar, a food offering with a pleasing aroma to the LORD.
Song of Songs 3:6–7, 9
What is that coming up from the wilderness
like columns of smoke,
perfumed with myrrh and frankincense,
with all the fragrant powders of a merchant?
Behold, it is the litter of Solomon!
King Solomon made himself a carriage
from the wood of Lebanon.
Hosea 14:4–7
I will heal their apostasy;
I will love them freely,
for my anger has turned from them.
I will be like the dew to Israel;
he shall blossom like the lily;
he shall take root like the trees of Lebanon;
his shoots shall spread out;
his beauty shall be like the olive,
and his fragrance like Lebanon.
They shall return and dwell beneath my shadow;
they shall flourish like the grain;
they shall blossom like the vine;
their fame shall be like the wine of Lebanon.
Psalm 72:1, 15–17, 20
Of Solomon.
Give the king your justice, O God,
and your righteousness to the royal son!
Long may he live;
may gold of Sheba be given to him!
May prayer be made for him continually,
and blessings invoked for him all the day!
May there be abundance of grain in the land;
on the tops of the mountains may it wave;
may its fruit be like Lebanon;
and may people blossom in the cities
like the grass of the field!
May his name endure forever,
his fame continue as long as the sun!
May people be blessed in him,
all nations call him blessed!
The prayers of David, the son of Jesse, are ended.

and the shadows flee,

and the hill of frankincense.
