Isaiah 11.1-12
From a ditty that I wrote last night for Victor Paul Furnish
"The LXX parallel [to 2 Thess 2.1-12] is in Isaiah 11.4 which describes the root of Jesse, avlla. krinei/ tapeinw/| kri,sin kai. evle,gxei tou.j tapeinou.j th/j gh/j kai. pata,xei gh/n tw/| lo,gw| tou/ sto,matoj auvtou/ kai. evn pneu,mati dia. ceile,wn avnelei/ avsebh/, but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; and he shall strike the earth with the rod of his mouth, and with the breath of his lips he shall kill the wicked. This is used in Christian tradition as prophesy fulfilled by Christ. Ellis finds this tradition in Matt 2.23 [Ellis, Pauls Use of the OT, 44, 105]; Rom 15.12 [Ellis, 57]; Eph. 6.14a [which is interesting for its mention of armor, cf. 1 Thess 5.8; Isa. 11.5; Ellis, 154]; Rom 15.12 [Isa 11.10; Ellis 151]. It is interesting that the tradition is in a Gospel, Paul, and deutero-Pauline material."
Matthew 2.23 (ESV)
23And he went and lived in a city called Nazareth, that what was spoken by the prophets might be fulfilled: "He shall be called a Nazarene."
Allusion to Isaiah 11.1-12
1There shall come forth a shoot from the stump of Jesse,
and a branch from his roots shall bear fruit.
2And the Spirit of the LORD shall rest upon him,
the Spirit of wisdom and understanding,
the Spirit of counsel and might,
the Spirit of knowledge and the fear of the LORD.
3And his delight shall be in the fear of the LORD.
He shall not judge by what his eyes see,
or decide disputes by what his ears hear,
4but with righteousness he shall judge the poor,
and decide with equity for the meek of the earth;
and he shall strike the earth with the rod of his mouth,
and with the breath of his lips he shall kill the wicked.
5Righteousness shall be the belt of his waist,
and faithfulness the belt of his loins.
I think that the argument is that Jesse has a regional association with Nazareth. In any case, Jesse was from Bethlehem, which obviously is associated with the birthplace of Jesus of Nazareth.
