And the city was broken up, and all the men of war fled by night by the way of the gate between two walls, which is by the king's garden: (now the Chaldees were against the city round about:) and the king went the way toward the plain.
The city was broken up - i:e., a breach was effected, as we are elsewhere informed, in a part of the wall belonging to the lower city (2 Chronicles 32:5; 2 Chronicles 33:14).
The gate between two walls, which is by the king's garden. The king's garden was (Nehemiah 3:15) at the Pool of Siloam-i e., at the mouth of the Tyropoeon, and extended thence to the defile in which En-rogel is situated. A trace of the outermost of these two walls appears to be still extant in the rude pathway which crosses the mouth of the Tyropoeon, on a mound hard by the old mulberry, tree which marks the traditional spot of Isaiah's martyrdom (Robinson's 'Biblical Researches,' p. 388; Barclay's 'City of the Great King,' p. 92; Porter's 'Handbook,' pp. 94, 95; Stewart's 'Tent and Khan,' p. 271). It is probable that the besiegers had overlooked this pass.
The king went ... toward the plain - i:e., the Ghor, or valley of Jordan, estimated at 5 hours' distance from Jerusalem. The plain near Jericho is about 11 or 12 miles wide.
