Dear Doves:
 
Israel's Valentine Day of Tu B'Av was originated from the event of Judges 21:21 that

Benjamin males ran off with daughters of Shiloh and the tribe of Benjamin was saved

from extinction.
The tribe of Benjamin was the smallest, yet known as loyal and faithful, and joined
the King David of Judah who is a "type" of Yeshua.
 
We all know that the Bride of the Philadelphia Church will be the helping partner to
reign the world with Yeshua, the King. 
And Revelation 3:8 shows a connection between the tribe of Benjamin and the
Philadelphia church.
 
"I know that you have little strength, yet you have kept my word and have not
  denied my name"
 
Hopefully the Bride is chosen on this Tu B'Av.
 
Maranatha!
