In Numbers 30, we have God's commandments regarding oaths.
According to these commandments, a man is directly bound to fulfill his oaths, but a woman's oaths must be approved of by her father if she is still in his care, or by her husband when the father hands her care over to him.
The approval of a father is given if he "holds his peace" on first hearing of his daughter's oath, or of a husband if he "makes no response" on first hearing of his wife's oath.
In regard to a widowed or divorced woman, if it can be established that her husband did not approve of her oath when he was alive, then she will not be bound by it (Numbers 30:9-12).
Reading Stephen Edwin Banks' 1895 thesis entitled, "Development of the Law Pertaining to the Contracts of Married Women", demonstratesit can be seen that these ancient commandments eventually found their way into Anglo-Saxon law.
The requirement of approval was not intended to disempower a woman, but to protect her from being preyed upon. This aspect of the law has all but been forgotten in modern society, whichwhere one can see it is of the greatest benefit to unscrupulous agencies for it remain so.
Conclusion
A father walking his daughter down the aisle and giving her to the groom is the modern equivalent of the Jewish practice of passing on the responsibility for a daughter's protection and welfare to another man -- one, of course, who would meet his approval.
