Genesis 21:4
“And Abraham circumcised his son Isaac being eight days old, as God had commanded him.”
KJV
Read in Genesis 21Meaning
Isaac receives the covenant sign according to the command previously given to Abraham in Genesis 17.
Read carefully
This is an ancient covenant practice within the narrative, not standalone modern medical advice or a basis for coercive medical decisions.
Reflection
The verse joins promise with obedience, showing that fulfillment does not erase the responsibilities already attached to the covenant.
