Eldad is mentioned 2 times in scripture, across 1 book of the Old Testament. First named in scripture around 1490 BC.
Whom God has loved, one of the seventy elders whom Moses appointed (Num. 11:26, 27) to administer justice among the people. He, with Medad, prophesied in the camp instead of going with the rest to the tabernacle, as Moses had commanded. This incident was announced to Moses by Joshua, who thought their conduct in this respect irregular. Moses replied, “Enviest thou for my sake? would God that all the Lord’s people were prophets” (Num. 11:24-30; comp. Mark 9:38; Luke 9:49).
