Jacob is the center of imagining in you, the inner self that quietly commands the outer world, and to bring Jacob again is to return your attention to that creative power instead of to appearances. Israel is what you want made real, the desire scattered through your mind and not yet gathered into one felt conviction. The servant formed from the womb is imagination itself, shaped for this single work of restoring a person to his own creative center.
Even when the desire is not yet gathered, the work already counts as done, for changing one state within proves the power and grants the reward before the whole is complete. Israel is what you want realized, and it is found within, never out on the visible earth. Your strength is the imagining self, and the moment it is honored, the outcome is assured.
