Researcher Uri Ofir deduced from this Menorah that " the sculptor of the Titus Gate created a lily that had 6 petals out of which we see only 3 in side projection". Uri Ofir claims that this is one of the proofs that the Star of David started from the Menorah.

Another ancient symbol of harmony and peace is the Menorah, the seven-branched candelabrum supported by three legs:
In our context, this may tell us that peace, betokened by the Menorah, cannot be established upon one or two legs; all three of them, symbolizing the three main descendants of Abraham and their respective religions, are required to reach a stable peace.
We may infer this from a saying by Solomon, the King of Peace, who said in his wisdom that "a threefold cord is not easily broken."
A mere changing or redesigning of symbols will not do. The actual change requires a relearning which would indeed be the learning of the ways of the God of Jacob, as enjoined by the Prophets. Such a process of reeducation may last for several generations, till we can really "beat the swords into plough shares."
While Christians have at least begun this process through events such as the Vatican Council II and the recent declarations of several Protestant Churches, the Islamic world still needs a harbinger for this new age of grace and truth, righteousness and peace.
May it be God's Will that Mankind comes to understand this without another destructive and devastating war.
