A Branch will grow from the sawn off stump of Jesse (father of David and thus of the line of Kings in Judea). so from what seems dead will come a new leader. There were a few good and lots of bad kings along the line of David – even the good kings had flaws.
but here is the description of a leader:
1 A shoot will come up from the stump of Jesse;
from his roots a Branch will bear fruit.
2 The Spirit of the LORD will rest on him—
the Spirit of wisdom and of understanding,
the Spirit of counsel and of might,
the Spirit of the knowledge and fear of the LORD—
3 and he will delight in the fear of the LORD.
The result will be Peace in un-natural ways – which means that nature itself will have to be transformed.
6 The wolf will live with the lamb,
the leopard will lie down with the goat,
the calf and the lion and the yearling together;
and a little child will lead them.
7 The cow will feed with the bear,
their young will lie down together,
and the lion will eat straw like the ox.
This is not accomplished at the ballot box, not at the point of a bayonet. But it is accomplished by the knowledge of God.
8 The infant will play near the cobra’s den,
and the young child will put its hand into the viper’s nest.
9 They will neither harm nor destroy
on all my holy mountain,
for the earth will be filled with the knowledge of the LORD
as the waters cover the sea.
