What was the sign given to Abraham to signify his covenant with God?

The sign given to Abraham to signify his covenant with God is circumcision. This practice was established in the book of Genesis, specifically in Genesis 17, where God commands Abraham to circumcise himself and the males in his household as a physical symbol of the covenant between them. This act served not only as a personal commitment from Abraham and his descendants to uphold the covenant but also as a distinguishing marker for God's chosen people. Circumcision represented their faithfulness and set them apart from other nations.

The significance of this sign lies in its deep-rooted meaning within the context of the covenant; it symbolizes the idea of being set apart for God and denotes a physical manifestation of a deeper spiritual commitment. This practice continued as a vital element of Jewish identity and heritage. In contrast, options like baptism, sacrifice, and ritual offering do not specifically relate to Abraham's covenant with God; they are associated with different aspects of faith and worship within the broader biblical narrative.
