Charles Ellicott Commentary Numbers 30:13

"Every vow, and every binding oath to afflict the soul, her husband may establish it, or her husband may make it void." — Numbers 30:13 (ASV)

Every vow, and every binding oath to afflict the soul.— Reference is again made to the two kinds of vows which are discussed in this chapter—namely, a vow to do anything, and a vow to abstain from anything.
