Numbers 11:25
24 So Moses went out and told the people the words of the Lord. He then gathered seventy men of the elders of the people and had them stand around the tabernacle. 25 And the Lord came down in the cloud and spoke to them, and he took some of the Spirit that was on Moses and put it on the seventy elders. When the Spirit rested on them, they prophesied, but did not do so again. 26 But two men remained in the camp; one’s name was Eldad, and the other’s name was Medad. And the Spirit rested on them. (Now they were among those in the registration, but had not gone to the tabernacle.) So they prophesied in the camp.
Onkelos Numbers 11:25
24 And Mosheh went forth, and told the people the words of the Lord, and gathered together seventy men of the elders of the people, and set them round about the tabernacle. 25 And the Lord was revealed in the Cloud, and spake with him, and he made enlargement of the Spirit that was upon him, and imparted to the seventy men, the elders; and it came to pass that when the Spirit of prophecy rested upon them they prophesied, and ceased not. 26 But two men remained in the camp, the name of the one Eldad, and the name of the second Medad; and the Spirit of prophecy rested upon them; and, though they were in the writings, they had not come out of the camp; but they prophesied in the camp.
Notes and References
"... The Targum, Targum Pseudo-Jonathan, and the Vulgate read “they did not cease prophesying,” presumably taking the verb to be יָסֻפוּ (yasufu; from סוּף; suf). This does not represent a change in the consonantal text, only in the vowels, which were not originally written. The Hebrew verb סוּף is rare (occurring) and appears to mean “to come to an end; to perish” ..."
