And there ran a young man, and told Moses, and said, Eldad and Medad do prophesy in the camp.

And when they prophesied in the camp, there ran a young man, and told Moses, saying: Eldad and Medad prophesy in the camp.

And there ran a youth, and told Moses, and said, Eldad and Medad are prophesying in the camp.

and the young man runneth, and declareth to Moses, and saith, 'Eldad and Medad are prophesying in the camp.'

And a young man went running to Moses and said, Eldad and Medad are acting as prophets in the tent-circle.

And when they were prophesying in the camp, a boy ran and reported to Moses, saying: "Eldad and Medad prophesy in the camp."

Et cucurrit puer quidam, et nuntiavit Mosi, dixitque: Eldad et Medad prophetant in castris.

Eldad and Medad do prophesy, etc. -
Eldad, they said, and Medad there,
Irregularly bold,
By Moses uncommission'd, dare
A separate meeting hold!
And still whom none but heaven will own.
Men whom the world decry,
Men authorized by God alone,
Presume to prophesy!

And there ran a young man,.... From the camp to the tabernacle, who had heard Eldad and Medad prophesy; which he thought was not right, being done without the knowledge and approbation of Moses, and in a private tent in the tabernacle, not among the elders, but the common people: who this young than was is not material to know; some of the Rabbins, as Jarchi says, affirm he was Gershon the son of Moses; whoever he was, no doubt, it was with a good design, consulting the glory of God and the honour of Moses, and therefore in great haste ran to him with the information:
and told Moses, and said, Eldad and Medad do prophesy in the camp; who seem by this, to be persons well known, and of some note and figure; since not only the young man could call them by their names, but there needed no other description of them to Moses and those with him.

Told Moses - Fearing lest his authority should be diminished by their prophesying; and thereby taking authority to themselves without his consent.
