Ben Sira 48:17

17 Hezekiah fortified his city, and brought water into its midst; he tunneled the rock with iron tools, and built cisterns for the water.

Ben Sira 48:17 In-Context

15 Despite all this the people did not repent, nor did they forsake their sins, until they were carried off as plunder from their land, and were scattered over all the earth. The people were left very few in number, but with a ruler from the house of David.
16 Some of them did what was right, but others sinned more and more.
17 Hezekiah fortified his city, and brought water into its midst; he tunneled the rock with iron tools, and built cisterns for the water.
18 In his days Sennacherib invaded the country; he sent his commander and departed; he shook his fist against Zion, and made great boasts in his arrogance.
19 Then their hearts were shaken and their hands trembled, and they were in anguish, like women in labor.
