¹ tn Or “tunnels.” The word is יְאֹרִים (y^eʾorim), the word for “rivers” and in the singular, the Nile River. Here it refers to tunnels or channels through the rocks.

² sn If a water tunnel is in view here, it is probably the so-called Warren’s Shaft that extends up from Hezekiah’s tunnel. It would have provided a means for surprise attack against the occupants of the City of David. The LXX seems not to understand the reference here, translating “by the water shaft” as “with a small knife.”

¹ tn The Hebrew word translated “Siloam” is הַשֶּׁלַח (hashelakh, “water-channel”; cf. ASV, NASB, NRSV, TEV, CEV “Shelah”). It apparently refers to the Pool of Siloam whose water supply came from the Gihon Spring via Hezekiah’s Tunnel built in 701 b.c. (cf. Isa 8:6). See BDB 1019 s.v. שִׁלֹחַ; W. L. Holladay, Concise Hebrew and Aramaic Lexicon, 372. On the etymology of the word, which is a disputed matter, see HALOT 1517 s.v. III שֶׁלַח.

² tn The term “pool” (בְּרֵכָה, b^erekhah) usually refers to a man-made artificial water reservoir fed by water aqueducts rather than to a natural pond (HALOT 161 s.v.). For example, it is used in reference to man-made water reservoirs for the royal gardens (Eccl 2:6; Neh 2:14); man-made water reservoirs in Jerusalem, some of which were fed by aqueducts (2 Kgs 18:17; 20:20; Isa 7:3; 22:9, 11; 36:2; Neh 3:15, 16); the pool of Gibeon (2 Sam 2:13); the pool of Hebron (2 Sam 4:12); the pool of Samaria (1 Kgs 22:38); and the pools of Heshbon (Song 7:5). The pool of Siloam, built by Hezekiah and fed by the underground aqueduct known as Hezekiah’s Tunnel, is designated by the term בְּרֵכָה in 2 Kgs 20:20 and the Siloam Inscription (line 5).
