God commands Abraham to circumcise every male in his household as a sign of the covenant. This physical sign is to be an everlasting covenant in the flesh of Abraham's descendants.
Theological significance

Theological significance
The name change signifies God's power to bring life and blessing. The promise of Isaac underscores God's ability to fulfill His promises despite human limitations.

In the broader story
Ishmael's blessing highlights God's inclusive nature and foreshadows the inclusion of Gentiles in the New Covenant through Christ.
