According to Moses, Abraham was 99 years old when he was circumcised, which shows his obedience to God's commands. This act was important because it was part of God's promise and special agreement with Abraham and his family.
Genesis 17:24: And Abraham [was] ninety years old and nine, when he was circumcised in the flesh of his foreskin.
This passage suggests urgency and divine anger related to circumcision, potentially conflicting with the orderly and willing circumcision in Genesis 17:24.
Exodus 4:24-26: And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.
