The methods used today to circumcise removes much more of the foreskin than required by the bible. Men who had been circumcised during biblical times appeared intact.
"The Biblical technique of circumcision designed to fulfill the Covenant with Abraham removed only preputial tissue that extended beyond the tip of the glans penis (Bris Milah). By first pulling up on the foreskin, then placing a glans shield, the operator preserved virtually all of the sensitive inner lining of the prepuce. ... sensitive tissue that was preserved during Biblical circumcision, is almost always excised during "modern" circumcision with the Gomco Clamp or the Plastibell....The Biblical technique was completed much more quickly. Part of the foreskin is slid into the slit on the shield, and a knife slices off the portion above the shield in less than one second. Gomco Clamp circumcisions have been known to take up to 20 minutes. ..." - George C. Denniston, M.D. M.P.H. "Modern" Circumcision: The Escalation of a Ritual
