Agur in the Bible Encyclopedia - ISBE

a'-gur ('aghur, seeming, from comparison with Arabic roots, to mean either "hireling," or "collector," "gatherer"): One of the contributors to Proverbs; his words being included in Prov 30. He takes an agnostic attitude toward God and transcendent things, and in general the range of his thought, as compared with that of other authors, is pedestrian. He shows, however, a tender reverence and awe. His most notable utterance, perhaps, is the celebrated Prayer of Agur (Prov 30:7-9), which gives expression to a charming golden mean of practical ideal. His sayings are constructed on a rather artificial plan; having the form of the so-called numerical proverb. See under PROVERBS, THE BOOK OF, II, 6. John Franklin Genung
