SHAFT [isbe]
SHAFT - shaft: Isa 49:2 for chets, "an arrow"; also Ex 25:31; 37:17; Nu 8:4 the King James Version for a part of the candlestick of the tabernacle somewhat vaguely designated by the word yarekh, "thigh." The context in the first 2 verses shows that the upright stem or "shaft" is intended, but in Nu 8:4 a different context has caused the Revised Version (British and American) to substitute "base."See also ARCHERY; ARMOR, ARMS.
