And the Lord said unto Moses, Gather unto me seventy men of the elders of Israel, whom thou knowest to be the elders of the people, and officers over them; and bring them unto the tabernacle of the congregation, that they may stand there with thee. (Numbers 11:16)
This is the word used of the Israelite foremen who worked under the Egyptian overseers (Ex. 5:15). The original meaning of the word is “arranger,”“organizer,”“secretary.”
