Num 2:25

The standard of … Dan. In the light of its subsequent history, it is remarkable that this tribe should at this time have been so prominent and so honoured. Dan is, so to speak; the Judas among the twelve. In history he ends by melting away into the heathen among whom he intruded himself. In the sacred writings he ends by being omitted altogether; he has no part in the new Jerusalem—perhaps on account of the idolatry connected with his name (see Jdg 18:1-31; Rev 7:1-17).
