            kan'-d'-l, kan'-d'-l-stik (ner; luchnos; menorah; luchnia):
(1) "Candle" is found in the Old Testament, the King James 
Version, as the rendering of ner, and in the New Testament 
for luchnos. In all places except Jer 25:10 and Zeph 1:12 
(see margin) the Revised Version (British and American) 
gives the more exact rendering "lamp." See LAMP. Candle, in 
our sense of the term, was unknown to antiquity.
(2) "Candlestick" stands for what was a common and 
indispensable article of ancient house furniture, a lamp-
stand (menorah). Accordingly we find it mentioned in a case 
thoroughly representative of the furnishings of an oriental 
room of the plainer sort, in the account of "the prophet's 
chamber" given in 2 Ki 4:10. Here we find that the furniture 
consisted of a "bed," a "table," a "seat," and a 
"candlestick," or lamp-stand. The excavations of Petrie and 
Bliss at Lachish (Tell el-Hesy, 104), not to mention others, 
help to make it clear that a lamp-stand is meant in passages 
where the Hebrew word, menorah, or its Greek equivalent 
luchnia, is used. Accordingly throughout the New Testament, 
the Revised Version (British and American) has consistently 
rendered luchnia by "stand" (Mt 5:15; Mk 4:21; Lk 8:16; 
11:33).
(3) The "candlestick" of Dan 5:5 is rather the candelabrum 
(nebhrashta') of Belshazzar's banqueting-hall. The "golden 
candlestick" of the tabernacle and the temple requires 
special treatment.
See CANDLESTICK, THE GOLDEN; TABERNACLE.
(4) Certain figurative uses of "candle" and "candlestick" in 
the Bible demand attention. The ancient and still common 
custom of the East of keeping a house lamp burning night and 
day gave rise to the figure of speech so universally found 
in oriental languages by which the continued prosperity of 
the individual or the family is set forth by the perennially 
burning lamp (see Job 29:3; "when his lamp shined upon my 
head"; Ps 18:28 "Thou wilt light my lamp"). The converse in 
usage is seen in many passages--(see Job 18:6; "His lamp 
above him shall be put out"; 21:17: "How oft is it that the 
lamp of the wicked is put out"; Prov 24:20; "The lamp of the 
wicked shall be put out"; Jer 25:10; "Take from them .... 
the light of the lamp"). The same metaphor is used in Rev 
2:5 to indicate the judgment with which the church of 
Ephesus was threatened: "I will move thy candlestick out of 
its place." "The seven golden candlesticks" (Rev 1:20) which 
John saw were "the seven churches," the appointed light-
bearers and dispensers of the religion of the risen Christ. 
Hence, the significance of such a threat.
