Hell is not a Jewish concept. Hell was introduced at the time of Christ.
Wrong, as is most everything you claim about Christianity and Judaism.

22 For a fire is kindled in mine anger, and shall burn unto the lowest hell, and shall consume the earth with her increase, and set on fire the foundations of the mountains.

6 The sorrows of hell compassed me about; the snares of death prevented me;
KJV
Job 11:8
8 It is as high as heaven; what canst thou do? deeper than hell; what canst thou know?
KJV
Job 26:6
6 Hell is naked before him, and destruction hath no covering.

Prov 27:20
20 Hell and destruction are never full; so the eyes of man are never satisfied.
KJV
Prov 5:5
5 Her feet go down to death; her steps take hold on hell.

9 Hell from beneath is moved for thee to meet thee at thy coming: it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations.
