Foreskin, apart from its literal meaning, functions in Tanach also as a metaphor of blemish. Similarly, the circumcision is presented as a removal thereof. The perfecting function of the rite is visible in Second Temple texts, as well as in later tannaitic sources. The purpose of this paper is to analyze words of Jesus found in J 7:22–23 in the light of circumcision in the Hebrew Bible, understood as a ritual performed to remove a blemish. The conclusion is that Jesus’ words in the analyzed verses continue the biblical view, attesting to an exegetical trend visible in later Jewish sources.
