Genesis 21:4
“Abraham circumcised his son, Isaac, when he was eight days old, as God had commanded him.”
What does Genesis 21:4 mean?
Abraham followed through on God's command immediately, circumcising Isaac at just eight days old. This act marked Abraham's obedience and sealed the covenant promise God had made to him, dedicating his long-awaited son to God from infancy. For Abraham's family and descendants, circumcision became the physical sign of belonging to God's people and honoring the ancient agreement between them. It shows how seriously Abraham took his faith, not delaying or second-guessing the difficult things God asked of him.
