Bowl : The sockets of the lamps of the golden candlestick of the tabernacle are called bowls (Exodus 25:31,33,34; 37:17,19,20); the same word so rendered being elsewhere rendered "cup" (Genesis 44:2,12,16), and wine "pot" (Jeremiah 35:5). The reservoir for oil, from which pipes led to each lamp in Zechariah's vision of the candlestick, is called also by this name (Zechariah 4:2,3); so also are the vessels used for libations (Exodus 25:29; 37:16).
