Which maketh Arcturus... — This shows us that in the time of this writer, whoever he was, his fellow-countrymen had attained to such knowledge of astronomy as is here implied in the specific names of definite constellations. The Great Bear is the glory of the northern hemisphere, Orion of the southern sky, and the Pleiades of the east; the chambers of the north are the unknown and unexplored regions, of which the speaker has no personal experience.
