And it happened on the eighth day [i.e., since the baby was born] that they came to circumcise the child [i.e., to perform the Jewish rite of identity, signifying the responsibility to observe the law of Moses]. And they [i.e., probably the neighbors and/or relatives of Elizabeth and Zacharias] suggested that they name him Zacharias, after his father.

Eight days later it was time to circumcise Jesus [i.e., to perform the Jewish rite of identity, signifying the responsibility to observe the law of Moses], and they named Him Jesus, which was the name given by the angel before He was [even] conceived.

Now the practice of circumcision [i.e., the Jewish rite of identity, signifying the responsibility to observe the law of Moses] is worthwhile, providing you obey [the rest of] the law of Moses. But if you disobey the law, you might as well have never been circumcised.

Look, I Paul am telling you that, if you revert to [the practice of] circumcision [i.e., the Jewish rite of identity, signifying the responsibility to observe the law of Moses], then Christ's [sacrifice] will be of no value to you.
