¹ tn Heb “vow a vow.” The phrase תִּדֹּר נֶדֶר (tiddor neder, “to vow a vow”) is a Hebrew idiom in which the root נדר is repeated for emphasis. The construction is a cognate accusative (see IBHS 166-67 §10.2.1f). The verb נָדַר (nadar, “to vow”) refers to the action of making a solemn promise to the Lord to perform an action or offer a sacrifice, e.g., Lev 27:8; Num 6:21; 30:11; Deut 23:23-24; Jonah 2:10; Mal 1:14; Pss 76:12; 132:2; see HALOT 674 s.v. נדר. The noun נֶדֶר (“vow”) was a gift or offering promised to be given to the Lord (Num 30:3; Deut 12:11; 23:19; Isa 19:12; Nah 2:1 [ET 1:15]; Ps 61:6, 9); see HALOT 674–75 s.v. נֵדֶר. It usually was a sacrifice or free-will offering (Deut 12:6; Ps 66:13) that was often promised during times of pressure (Judg 11:30; 1 Sam 1:11; 2 Sam 15:7-8; Pss 22:25; 66:13; 116:14, 18; Jonah 2:9).

¹ tn There is some debate about the meaning of the verb here. Both BDB 172 s.v. גָּעַשׁ Hithpo and KBL 191 s.v. גָּעַשׁ Hitpol interpret this of the back and forth movement of staggering. HALOT 192 s.v. גָּעַשׁ Hitpo interprets it as vomiting. The word is used elsewhere of the up and down movement of the mountains (2 Sam 22:8) and the up and down movement of the rolling waves of the Nile (Jer 46:7, 8). The fact that a different verb is used in v. 27 for vomiting would appear to argue against it referring to vomiting (contra W. L. Holladay, Jeremiah [Hermeneia], 1:674; it is “they” that do this not their stomachs).
