Judith 7:12-22

12 Remain in your camp, and keep all the men in your forces with you; let your servants take possession of the spring of water that flows from the foot of the mountain,
13 for this is where all the people of Bethulia get their water. So thirst will destroy them, and they will surrender their town. Meanwhile, we and our people will go up to the tops of the nearby mountains and camp there to keep watch to see that no one gets out of the town.
14 They and their wives and children will waste away with famine, and before the sword reaches them they will be strewn about in the streets where they live.
15 Thus you will pay them back with evil, because they rebelled and did not receive you peaceably."
16 These words pleased Holofernes and all his attendants, and he gave orders to do as they had said.
17 So the army of the Ammonites moved forward, together with five thousand Assyrians, and they encamped in the valley and seized the water supply and the springs of the Israelites.
18 And the Edomites and Ammonites went up and encamped in the hill country opposite Dothan; and they sent some of their men toward the south and the east, toward Egrebeh, which is near Chusi beside the Wadi Mochmur. The rest of the Assyrian army encamped in the plain, and covered the whole face of the land. Their tents and supply trains spread out in great number, and they formed a vast multitude.
19 The Israelites then cried out to the Lord their God, for their courage failed, because all their enemies had surrounded them, and there was no way of escape from them.
20 The whole Assyrian army, their infantry, chariots, and cavalry, surrounded them for thirty-four days, until all the water containers of every inhabitant of Bethulia were empty;
21 their cisterns were going dry, and on no day did they have enough water to drink, for their drinking water was rationed.
22 Their children were listless, and the women and young men fainted from thirst and were collapsing in the streets of the town and in the gateways; they no longer had any strength.
