30:1-16 Vows were an important way to express devotion or piety, but were sometimes made in haste and were often forgotten. Voluntary pledges were commonly made on special religious occasions or in times of war. Perhaps the reference to vows and voluntary offerings (29:39) prompted the further discussion here (cp. 15:3; see also 6:1-21; Lev 5:4-5; 27:1-34; Deut 23:21-23). These instructions were applied in the case of Hannah and Elkanah (1 Sam 1:1-28). Such practices, which included fasting, continued into the New Testament period (e.g., Matt 6:16; 15:3-9; Acts 18:18; 21:23). Vows of females—young and unmarried or adult and married—were subject to approval by the responsible male who would be a financial partner in the vow. Nobody, male or female, young or old, should make a vow to God and then neglect it. 30:1-2 Vows included promises of offerings (e.g., Hannah’s vow, 1 Sam 1) and pledges of abstinence (e.g., the Nazirite vow, Num 6). Jesus made reference to the instruction regarding vows in the Sermon on the Mount (Matt 5:33).
