Ben Sira 48:17

17 Hezekiah fortified his city, and brought water into the midst of it; he tunneled the sheer rock with iron and built pools for water.

Ben Sira 48:17 In-Context

15 For all this the people did not repent, and they did not forsake their sins, till they were carried away captive from their land and were scattered over all the earth; the people were left very few in number, but with rulers from the house of David.
16 Some of them did what was pleasing to God, but others multiplied sins.
17 Hezekiah fortified his city, and brought water into the midst of it; he tunneled the sheer rock with iron and built pools for water.
18 In his days Sennacherib came up, and sent the Rabshakeh; he lifted up his hand 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 travail.
