Numbers 30:10

And if she vowed in her husband's house ,.... Before his death, in his lifetime, or before divorced: the Targum of Jonathan adds, by way of explanation, "and not at age for marriage", understanding it of a betrothed, and not a married person; but Jarchi says, the Scripture speaks of a married one, which seems most likely:

or bound her soul by a bond with an oath ; to fulfil her vow, to abstain from this, or to do that or the other thing.
