Though I might also have confidence in the flesh.
From the Jamieson-Fausset-Brown Bible Commentary (1871):
In three particulars he shows how he “might have confidence in the flesh” (Php 3:4): (1) His pure Jewish blood. (2) His legal preciseness and high status as such. (3) His zeal for the law. The Greek is literally, “Being in circumcision an eighth day person,” that is, not one circumcised in later life as a proselyte, but on the eighth day after birth, as the law directed in the case of Jew-born infants.
