Genesis 38:18

And he said, what pledge shall I give thee?.... Being willing to part with anything for the gratification of his lust:

and she said, thy signet, and thy bracelets, and thy staff that [is] in thine hand; she asks all these, that if one should be lost, or fail of being sufficient proof, the other might: the first of these the Septuagint version renders, "thy ring"; the ring upon his finger, which had a seal on it, and was the signet of his right hand; so Onkelos and Ben Melech: the second word seems not so well rendered, since "bracelets" were wore by women and not men: Jarchi takes it to be a garment with which he was covered; so Ben Melech and the Targum, a cloak, which is not likely, that she should desire him to strip off his clothes: it seems to be either a covering of his head, a wrap of linen such as the Turks wear, or else a handkerchief he had in his pocket; and the staff in his hand was either his walking staff or a shepherd's crook or staff:

and he gave [it] her, all the above things as a pledge:

and came in unto her; not on the public road, but in some private place at some distance, to which they retired. Maimonides c says, before the law was given, if a man met a woman in the street, and he and she agreed, he gave her hire, and he lay with her, and went away, and such an one was called "Kedeshah", a harlot, the word used afterwards for Tamar:

and she conceived by him; she proved with child upon it.
