Divine Name, The

In Jewish mysticism great stress is laid upon the importance of the Divine Name. It consists of forty-two letters; not, as Moses Maimonides points out, comprised in one word, but in a phrase of several words, which conveyed an exact notion of the essence of God. With the priestly decadence in the last days of the Temple, a name of twelve letters was substituted for the Divine Name, and as time went on even this secondary name was not divulged to every priest, but only to a few. The longer name was sometimes said to contain forty-five or seventy-two letters. The ten Sefiroth are also supposed, in a mystical sense, to be the names of the Deity. The Divine Name Jahveh is greater than "I am that I am, since the latter signifies God as He was before the creation, the Absolute, the Unknowable, the Hidden One; but the former denotes the Supreme Manifestation, the immanence of God in the Cosmos. 66 66

Dixmude

a small town in the north of Belgium, about ten miles S. of Ostend and equally distant, in a northerly direction, from Ypres. It was the center of that little portion of the western edge of Belgium which the Belgian army was able to hold after the invasion of their country by the Germans, in the latter part of 1914, and was the center of a continuous struggle that lasted during the entire war. The Belgians were firmly intrenched here, and Dixmude was the center of the heaviest of the German artillery and infantry attacks. One of the biggest engagements fought on this sector was that which began on July 31, 1917, when the British and French forces launched their offensive against the Germans on a twenty-mile front, extending from Dixmude to Warneton, to the south, and which resulted in a notable victory, ten towns and 5,000 prisoners being captured during the first day.
