The Mekubalim know the definition of "power of Moshiach has been conceived", which is still not yet the Moshiach, it is Chezkat Moshiach. The person that received an addition soul, expresses an increase signal to his name by adding an additional letter, without change of pronounciation of his name, even after the increase of the letter. In the words of Rav Kaduri, the letter Vav was added on to the person's name. (Only in two names did we find an increase of the letter Vav not changing the sound of the name; Yaakov and Shilo).
Actually, there are the different spellings of the name Tzipor, although I suppose one could argue that in its first appearance (as a name or as a bird), it is spelled with a vav.
With the vav: Num 22:2, 4, 16; Jos 24:9; Jud 11:25
Without the vav: Num 22:10; 23:18
In verse 18, a vav is placed on ben, hence "beno Tzipor" (no vav in Tzipor), interpreted as indicating the Messiah's origins from Moab/Balak:
This week’s Torah portion involves Balak, son of Tzipor – a bird. “Due to the merit of the forty-two sacrifices that Balak brought, he was privileged to have King Shlomo as his offspring … Rabbi Yossie Ben Choni said, Ruth was the daughter of Eglon, the son of Balak.” [Sota 47a]. Thus, the soul of the Mashiach, symbolized by a bird, exists in Balak, and he is the one who is attempting to block him being revealed. Bilam says to him, “Listen to me, son of Tzipor” [Bamidbar 23:18] – but this can also be read as, “one who has a son named Tzipor.” And this phrase, “beno tzipor,” has a numerical value of 434, which is also the value of “Mashiach Ben David.”
Catch this detail, which appears at first to be an error...
“beno tzipor,” has a numerical value of 434
There's no vav in Tzipor. The sum of the phrase in the verse = 428.
Then again,
In the words of Rav Kaduri, the letter Vav was added on to the person's name.
In that case, the sum *is* 434, without change of pronounciation of his name, even after the increase of the letter.
The connected phrase “Mashiach Ben David” indicates that David is spelled with a yud. Thus it is equivalent to "Mashiach ben Dodi", the son of my beloved, the term of endearment for either lover in the Song of Solomon. Thus there are options, such as God, Israel, or the Shekinah, who is represented by the bird.
As far as the bird's nest, the kan (150, ק"ן), how it relates to important meetings and match-ups:
May 10, 2019 is the 150th anniversary of the completion of the transcontinental railroad. East meets West. It falls on the 71st birthday of the Medina. The bird that represents the Shekinah, the soul of the Mashiach, and the people of Israel is the dove, yonah, whose sum is 71.
More bird analogies:
The Spirit of God in Gen 1:2 is interpreted as the soul of the Mashiach, coming down and hovering like a dove [Rashi].
Ruach Elohim = 300 = the two wings [of the dove], as kanaf ("wing") = 150.
The female personification of America is Columbia ("dove").
What's in a name? Everywhere you find the tRuth, you find Ruth. It would certainly explain why the Mashiach descends directly from Ruth.
Moshiach is over my pay grade.
