'Almond tree' in the Bible

yes, they shall be afraid of heights, and terrors will 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 about the streets:

Moreover the word of Yahweh came to me, saying, "Jeremiah, what do you see?" I said, "I see a branch of an almond tree."
