Circumcision on the 8th Day in Old Testament Scripture

The practice of circumcising male infants on the eighth day after birth is a specific divine command given to Abraham and later codified in the Mosaic Law, serving as a sign of the covenant between God and his chosen people [3, 4]. This rite was not merely a cultural practice but a divinely instituted ordinance, as recorded in Genesis 17:9-10 and Leviticus 12:3 [2].

The instruction for circumcision on the eighth day is explicitly stated in Leviticus 12:3: "In the eighth day the flesh of his foreskin shall be circumcised" [1]. This timing was a crucial aspect of the command. John Gill, in his commentary on Leviticus, suggests that one reason for the eighth-day timing might relate to the mother's period of separation and uncleanness, which would have ended by then [5]. He also notes that the circumcision of a male child on the eighth day was so religiously observed that it was not omitted even if the eighth day fell on the Sabbath [5, 7].

The institution of circumcision predates the Mosaic Law, originating with Abraham. God established it as a "national ordinance" and a "special badge" for his chosen people, signifying their consecration to him [4]. Abraham himself, at ninety-nine years old, was circumcised on the same day as Ishmael, who was thirteen [4]. All male slaves, whether born in the household or purchased, were also to be circumcised [4]. This covenant of circumcision was a necessary condition for Jewish nationality [3].

The significance of the eighth day has been a point of discussion among commentators. John Gill, in his commentary on Genesis 17:12, cites Maimonides, who suggested reasons for the timing: to prevent neglect if deferred to a riper age, to minimize pain due to the tenderness of the skin and weaker imagination of an infant, and to consider the parents' affections [8]. Calvin, while acknowledging the specific timing, also suggested that God might have had respect for the tender age of the infants, demonstrating his paternal love [6]. Adam Clarke points out that if circumcision were essential for an infant's salvation, God would not have delayed it to the eighth day, as many infants die before that age [11]. He draws a parallel to baptism, suggesting that both are signs of the covenant, with circumcision representing the putting away of fleshly impurity [11].

The Jewish tradition, as interpreted by Abraham Ibn Ezra, clarifies that "the eighth day" refers to the daylight hours, not necessarily a full twenty-four-hour period from birth. A child born a half-hour before sunset on day one would be circumcised after six and a half days, counting the partial first day as a whole day [12].

Circumcision was considered "the covenant of circumcision" [2, 13]. It was a "seal of the covenant" [2]. The Apostle Paul, in Philippians 3:5, emphasizes his own adherence to this command, stating he was "circumcised the eighth day," highlighting his Jewish identity and strict observance of the law [9, 10]. This practice distinguished Jews from Gentiles, who were referred to as "the uncircumcision" [3, 9].

The New Testament references circumcision in various contexts. Acts 7:8 mentions that Abraham "begat Isaac, and circumcised him the eighth day" [13]. Paul's reference in Philippians 3:5 underscores the importance of this specific timing within Jewish law [9, 10]. The Gospel of John also notes that the law required circumcision on the eighth day, even permitting it on the Sabbath [7]. Jesus used this allowance as a precedent for healing on the Sabbath, arguing from "the lesser to the greater" [7].

While circumcision was a physical rite, it also carried spiritual implications. Romans 2:28-29 distinguishes between outward circumcision of the flesh and an inward circumcision of the heart, which is by the Spirit [2]. This inward grace is contrasted with the outward sign [2]. The rite was a "painful and bloody" one [2], and it was a necessary condition for enjoying the privileges of the Jewish state [2].

The practice of circumcision on the eighth day, therefore, was a foundational element of the Old Testament covenant, deeply embedded in the identity and religious life of ancient Israel. It was a divine command given to Abraham, reiterated in the Mosaic Law, and meticulously observed, even taking precedence over the Sabbath [5, 7].

Some, however maintain that we must not contend earnestly about the number of days, because the Lord spared the children on account of their tenderness, since it was not without danger to inflict a wound upon those who were newly born. For although he might have provided that circumcision should produce no harm or injury; yet there would be no absurdity in saying, that He has respect to their tender age, in order to prove to the Jews his paternal love towards their children.

The reasons why this rite was ordered to be performed in infancy, according to Maimonides (d), were, because if it had been deferred to riper age it might have been neglected, and never performed; and because at such an age the pain is not so sensibly felt, by reason of the tenderness of the skin, and the weakness of the imagination; as also because the affections of parents are not th”
