hunting, and the wild game it yields: the chase itself and the meat a hunter brings home
This word names both sides of the hunt at once: the skill and activity of tracking wild animals, and the catch that results, the wild meat carried home to be cooked and eaten. Hebrew keeps the two together in a single word, so which side is in view depends on the sentence. When a person is called mighty or skilled at it, the activity is meant; when it is eaten or brought to a father, the game itself is meant.
Almost every occurrence sits in two stories. Nimrod is "a mighty hunter" at the dawn of the nations, and Esau is "a man who knew hunting," the brother whose wild game his father Isaac loved to eat. In the drama of the stolen blessing the word drums through the chapter as Isaac asks for game, Esau goes out to catch it, and Jacob arrives with a substitute dish.
The Bible's picture of the hunter is pointed. The two men who carry this word, Nimrod and Esau, stand at the edges of the covenant people, set in deliberate contrast to the shepherds, from Abel to David, whom the Bible holds up as its leaders. Related Hebrew words fill out the scene: the matching verb צוד, to hunt or chase, and טֶרֶף, the torn prey a wild predator rips from its kill.
