bek, bek'-'-n (neuma): This word from neuo, "to nod," "beckon," "make a sign" by moving the head or eyes (Luke 5:7 John 13:24 Acts 21:40; Acts 24:10), occurs only in 2 Maccabees 8:18, "Almighty God who at a beck can cast down both them that come against us, and also all the world," the Revised Version (British and American), "able at a beck." So Shak, "troops of soldiers at their beck"; "nod" is now generally used.
