The meaning of Almonds in the Bible

Numbers 17:8 (NIV) 

The next day Moses entered the tent and saw that Aaron's staff, which represented the tribe of Levi, had not only sprouted but had budded, blossomed and produced almonds.

Ecc 12:5 (NLT)

Remember him before you become fearful of falling and worry about danger in the streets; before your hair turns white like an almond tree in bloom, and you drag along without energy like a dying grasshopper, and the caperberry no longer inspires sexual desire. Remember him before you near the grave, your everlasting home, when the mourners will weep at your funeral.

Exodus 25:33 (NIV)

Three cups shaped like almond flowers with buds and blossoms are to be on one branch, three on the next branch, and the same for all six branches extending from the lampstand.

Exodus 37:19 (NIV)

Three cups shaped like almond flowers with buds and blossoms were on one branch, three on the next branch and the same for all six branches extending from the lampstand.

The almond tree is the first plant to flower in Greece, sometimes as early as mid-Janurary, and as such is a symbol of new life and fertility. Ancient Greek myths also link almonds, and the almond-shape, with new life; yet preceding all these in time, and succeeding them in importance, is the story of Aaron’s rod, which blossomed forth not only flowers, but almonds.

The almond tree is mentioned in Ecclesiastes 12:5, where in the description of old age it says "the almond-tree shall blossom." The reference is probably to the white hair of age. An almond tree in full bloom upon a distant hillside has a certain likeness to a head of white hair.

Bowls of lampstand in the tabernacle fashioned after the nuts of the almonds.

The Hebrew word for almond, shaked, is also translated “to watch”.

Matthew Henry's Concise Commentary
Jeremiah 1:11-19 God gave Jeremiah a view of the destruction of Judah and Jerusalem by the Chaldeans. The almond-tree, which is more forward in the spring than any other, represented the speedy approach of judgments.
