1 This chapter forms part of the story already begun. There are three major sections here: dissatisfaction with the reports (vv. 1–10), the threat of divine punishment (vv. 11–38), and the defeat of the Israelites (vv. 39–45). See K. D. Sakenfeld, “The Problem of Divine Forgiveness in Num 14,” 37 (1975): 317–30; also J. R. Bartlett, “The Use of the Word רֹאשׁ as a Title in the Old Testament,” 19 (1969): 1–10.
2 The two verbs “lifted up their voice and cried” form a hendiadys; the idiom of raising the voice means that they cried aloud.
3 There are a number of things that the verb “to weep” or “wail” can connote. It could reflect joy, grief, lamentation, or repentance, but here it reflects fear, hopelessness, or vexation at the thought of coming all this way and being defeated by the Canaanite armies. See Judg 20:23, 26.
