Based on this, the language of the piyut (liturgical poem) for the brit milah (circumcision) service fits well: "On a day of dry land, the depths turned, a new song the redeemed sang," which primarily speaks about the Song of the Sea. Within it, there is a stanza: "To whom is this recorded, recognize the true word, whose seal and whose cords," which speaks of Judah's confession in the incident with Tamar. At first glance, it seems puzzling—what is the connection between the Song of the Sea and Judah's confession? Simply, one could say it is only hinted at and refers to what was written earlier: "He showed their signs, to all who see them, and on the wings of their garments they shall make fringes." If so, this stanza is also an allegory for the commandments of circumcision and tzitzit (fringes).

However, according to our explanation, it can be interpreted further that mentioning Judah's confession of his sin within the piyut of the Song of the Sea hints at the idea that Judah's characteristic is to acknowledge the truth and do teshuvah (repentance). Because of this, the sea was split, for he had repented and corrected the sin of selling Yosef (Joseph).
