And this is due to their Avodah being incomplete in that they did not entirely refine the evil, so that as a consequence a nurture was possible to the L’umas Zeh' and so on.
However, regarding this very situation it says, "and You stood by them in the time of their distress, You waged their wars.” This means, that when the B’nei Yisroel were in a time of distress, they were on a very low level; consequently their Avodah was missing the 'battle' with the 'Le’umas Zeh'. That is [the time] when 'Ravtoh Es Rivom’ HaShem fought the battle which the B’nei Yisroel were supposed to fight.
In other words, the battle with the 'Le’umas Zeh' was carried out by Hashem in a manner of 'Isarusa Dele’eilah' an inspiration from above to below and as a result of this they were triumphant in the battle.
And even though it is known that the victory at war was due as a result of the Chashmonoim’s 'Mesiras Nefesh’ however, this was notwithstanding the fact that the ‘Mesiras Nefesh' here was only actually performed by a few and not by the majority, who were [as aforementioned] on a very low spiritual level. [This is unlike the situation in the story of Purim whereby the ‘Mesiras Nefesh' was not only performed by Mordechai and Esther, but by all the B’nei Yisroel]. And even the ‘Mesiras Nefesh’ which was performed by the few, did not suffice to bring about the miracle, because the miracle was wholly an `Isarussa Dile`eila’- an act of Divine intervention - and the ‘Mesiras Nefesh' was only necessary to serve as a receptacle in which to receive the revelation that was extended from above in a manner of 'Isarusa Dil'eilah'.
And this is because, since the revelation that is extended from above that came in a manner of an ‘Isarussa Dil’eilah’- an arousal from above, therefore it is spiritually even higher than the 'Seder Hishtalshelus'.
So, in order to prepare a receptacle which can receive such a level of revelation it would not be enough to perform a regular 'Avodah' on a level of understanding and attainment, within the confines of measurement and limitation, because it just will not suffice.
However, there is a vessel, the only vessel that could contain this light, and this is the vessel of 'Mesiras Nefesh' which is above and beyond 'Measurements and limitation'.
