bat-Shua bore Yehuda short-lived sons
who sired no grandsons to enlarge the clan
he had to show them how the deed is done
the tribal staff's upheld by just one man
the mamzer twins got nations of their own
while their half-brothers languished by the Nile
the lines that would rejoin in David's throne
must go their sep'rate ways for quite a while
a plea to reunite the kingdoms twain
as Yosef wields the powers they once had
whom they'd betrayed when he was but a swain
Yehuda invokes memories of dad
'though sire and son went in to the same girl
their seed begot Moshiach for the world
