That the passages are stopped. — These were probably the ferries across the Euphrates, by which one part of the city was in communication with the other. These were at the ends of the streets that ran at right angles to the river, and gates — left open in the panic of surprise — led down to them. Besides these there was one bridge over the Euphrates in the middle and a tunnel under it (Herod. i. 186). The word is elsewhere used for fords, as in Genesis 32:22; Judges 3:28, but cannot have that meaning here, as the Euphrates was not fordable at Babylon.
The reeds they have burned with fire. — The word for “reeds” is elsewhere (Isaiah 14:23; Isaiah 41:18; Exodus 7:19; Exodus 8:5) translated “pool.” Here it probably refers to the great pool constructed by Nitocris as a reservoir or dock. This was probably left dry by the diversion of the river into another channel, and the reeds which grew in it, perhaps also the flood-gates of the canals, and the ships that were in dock, were burnt by the Persians. The very pools were the scene of a conflagration.
