Early Hebrews are known for being the first in history to believe in a single, all-powerful, all-present God. The predecessor of this belief is priest Melchizedek, the ancient king of still non-Jewish Jerusalem, who welcomed Abraham during his return from the wars. This religion, known as Judaism, is the first monotheistic religion, has been established many centuries after Abraham as the official religion of the Jews, by Moses.
