Genesis 38:16

And he turned unto her by the way, and said, Go to, I pray thee, let me come in unto thee; (for he knew not that she [was] his daughter in law.) And she said, What wilt thou give me, that thou mayest come in unto me?

Ver. 16. Let me come in unto thee.] This is recorded, (1.) To cut the comb of those proud Jews, that glory so much of their pedigree, and name of Judah. How could they say, "We be not born of fornication?" Joh 8:41 (2.) To mind us that there is no Church to be found on earth without blot and blemish. (3.) That we may consider and admire the utter abasement of our Lord Christ, who would be born, not only of holy, but of impure parentage. And this, to show, [1.] That he borrowed no grace or glory from his progenitors, and as he needed not to be ennobled, so neither was he disparaged by them; [2.] That by his purity and passion all our sins are expiated and done away; like as the sun cleareth whatsoever filth is found in the air or on the earth. Three women only are mentioned in his genealogy; Rahab the harlot, Bathsheba the adulteress, and this incestuous Tamar; Matthew 1:3 ; Mat 1:5-6 to show his readiness to receive the most notorious offenders, that come unto him with bleeding and believing hearts. 1Ti 1:15
