C. F. Keil and Franz Delitzsch on Deuteronomy 22:23-24

Deu 22:23-24

If a betrothed virgin had allowed a man to have intercourse with her (i.e., one who was not her bridegroom), they were both of them, the man and the girl, to be led out to the gate of the town, and stoned that they might die: the girl, because she had not cried in the city, i.e., had not called for help, and consequently was to be regarded as consenting to the deed; the man, because he had humbled his neighbour’s wife. The betrothed woman was placed in this respect upon a par with a married woman, and in fact is expressly called a wife in Deu 22:24. Betrothal was the first step towards marriage, even if it was not a solemn act attested by witnesses. Written agreements of marriage were not introduced till a later period (Tobit 7:14; Tr. Ketuboth i. 2).
