Mention being made, in the latter part of the preceding chapter, of vows to be performed to the Lord, besides the sacrifices directed to; here some account is given of them, and men are charged to fulfil, and not break them, Nu 30:1 but as to women, if a maid, being in her father's house, made a vow in his hearing, and he silent at it, her vow stood; but if he disapproved of it, it was null and void, Nu 30:3 and so a wife, when she vowed a vow in the hearing of her husband, and he said not ought against it, it was valid; but if he objected to it, it stood for nothing, Nu 30:6, likewise a widow, or one divorced, that made a vow in her husband's house, before he died, or she was put away from him, and he did not contradict it, it remained in force and to be fulfilled; but if he made it void, it stood not, and she was forgiven, Nu 30:9 it being in an husband's power to confirm or make null a vow or oath, made by his wife to afflict her soul; but if he made any void after he heard them, and had been silent, he himself was to bear her iniquity, Nu 30:13.
Ver. 1. And Moses spake unto the heads of the tribes,.... Or the princes of them, who could more easily be convened, and who used to meet on certain occasions, and on whom it lay to see various laws put in execution:concerning the children of Israel; how they ought to conduct and behave in the following case, it being an affair which concerned them all:saying, this is the thing which the Lord hath commanded; relating to vows.
