갈대아 사람이 그 성읍을 에워쌌으므로 성벽에 구멍을 뚫은지라 모든 군사가 밤중에 두 성벽 사이 왕의 동산 곁문 길로 도망하여 아라바 길로 가더니

By way of the gate between the two walls. A cave went from his house until the Plains of Yericho, and he fled through the cave. The Holy One, Blessed Is He, ordained a deer walking on the roof of the cave. and the Kasdim pursued the deer, and when they reached the cave's entrance in the Plains of Yericho, they saw him and captured him. This is what [Scripture] states, ”And I will spread My net over him, and he shall be caught in My snare.”2Yechezkeil 12:13.
