He will also be a spirit of justice
for whoever sits as a judge,
and a source of strength for those
repelling enemy attacks at the gate.
Remember what Moshe asked before he went back to Egypt to deliver Israel from bondage? He asked what name he should give to the leaders of the People of Israel. The most common translation is “I AM,” but the Hebrew eheyeh asher eheyeh means “I will be what I will be.” This answer is vague, but we see through the account of the plagues, the sojourn through the wilderness and passages like this, that the true meaning of that name is that the Almighty is so great and so far beyond us, that whatever need is at hand, He is more than equal to the task. The Almighty was, is and always will be exactly who and what those who love and fear Him need Him to be.
