Numbers 11:26

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, ¹  but had not gone to the tabernacle.) So they prophesied in the camp.

Ex 3:11; Ex 4:13,14; 1Sa 10:22; 1Sa 20:26; Jer 1:6; Jer 36:5

¹ tn The form of the word is the passive participle כְּתֻבִים (kÿtuvim, “written”). It is normally taken to mean “among those registered,” but it is not clear if that means they were to be among the seventy or not. That seems unlikely since there is no mention of the seventy being registered, and vv. 24-25 says all seventy went out and prophesied. The registration may be to eldership, or the role of the officer.
