Exodus 27:20
pure oil ... pressed olives <08081 02132 03795 02134> [pure oil olive beaten.]
That is, such oil as could be easily expressed from the olives, after they had been bruised in a mortar; and which is much purer than that obtained after the olives are put under the press.
light <03974> [for the light.]
lamps <05216> [to cause the lamp.]
Josephus says, that the whole of the seven lamps burned all night; and that in the morning four were extinguished, and three burned the whole of the day. Such might have been the practice in his time; but it appears sufficiently evident from ch. 30:8, and 1 Sa 3:3, that they were anciently extinguished in the morning.
burn <05927> [to burn. Heb. to ascend up.]
