Exodus 22:16

If a man entice a maid. — The seduction of a maiden is regarded more seriously in primitive than in more advanced communities. The father looked to receive a handsome sum (ἕδνα) from the man to whom he consented to betroth his virgin daughter; and required compensation if his daughter’s eligibility as a wife was diminished. If the seducer were a person to whom he felt it a degradation to marry his daughter, he might exact from him such a sum as would be likely to induce another to wed her; if he was one whom he could accept as a son-in-law, he might compel him to re-establish his daughter’s status by marriage. It might be well if modern societies would imitate the Mosaic code on this point by some similar proviso.

He shall surely endow her — i.e., pay the customary sum to the father. See Deuteronomy 22:29, where the sum is fixed at fifty shekels of silver.
