According to the Old Testament, the almond symbolised watchfulness and promise.
Jeremiah 1:11-12: The word of the Lord came to me: “What do you see, Jeremiah?”
“I see the branch of an almond tree,” I replied.
The Lord said to me, “You have seen correctly, for I am watching to see that my word is fulfilled.”
In the Book of Genesis, the almond is “among the best of fruits.”
Moses (Numbers 17:8) was delighted to see “that Aaron’s staff, representing the house of Levi, had sprouted, formed buds, blossomed, and produced almonds!”
The menorah was based on the design of the almond blossom. (Exodus 25:33) “Three bowls made like unto almonds, with a knop and a flower in one branch; and three bowls made like almonds in the other branch, with a knop and a flower: so in the six branches that come out of the candlestick.
