'Almond tree' in the Bible

yea, they shall be afraid of height, and terrors [shall be] in the way, and the almond tree shall blossom, and the grasshopper shall be a burden, and desire shall fail, because man goes to his everlasting home, and the mourners go

Moreover the word of LORD came to me, saying, Jeremiah, what do thou see? And I said, I see a rod of an almond tree.
