2. Circumcision, while not exclusively a Hebrew or an Israelitish practise, was made a definite requirement through the revelations of God to Abraham, as the sign of the covenant between Jehovah and the patriarch. (Gen. 17:9-14.) This covenant was made to include the establishment of Abraham's posterity as a great nation, and provided that through his descendants should all nations of the earth be blessed (Gen. 22:18)--a promise which has been proved to mean that through that lineage should the Messiah be born. Circumcision was a binding condition; and its practise therefore became a national characteristic. Every male was to be circumcized eight days after birth (Gen. 17:12; Lev. 12:3). This requirement as to age came to be so rigidly enforced, that even if the eighth day fell on a Sabbath the rite had to be performed on that day (John 7:22, 23). All male slaves had to be circumcized (Gen. 17:12, 13) and even strangers who sojourned with the Hebrews and desired to partake of the Passover with them had to submit to the requirement (Exo. 12:48). From the _Standard Bible Dictionary_ we take the following: "The ceremony indicated the casting off of uncleanness as a preparation for entrance into the privileges of membership in Israel. In the New Testament, with its transfer of emphasis from the external and formal to the inner and spiritual side of things, it was first declared unnecessary for Gentile converts to the gospel to be circumcized (Acts 15:28), and afterward the rite was set aside even by Jewish Christians." It became customary to name a child at the time it was circumcized, as is instanced in the case of John, son of Zacharias (Luke 1:59). 3. Zacharias' Affliction.--The sign for which Zacharias asked was thus given by the angel: "Behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season." (Luke 1:20.) From the account of the circumcision and naming of the boy, John, it is held by some that the afflicted father was also deaf, as the company "made signs" to him as to how he would have his son named (verse 62).
