Luke explained what happened on the eighth day (Καὶ ἐγένετο ἐν τῇ ἡμέρᾳ τῇ ὀγδόῃ) after the birth of the child. They came to circumcise this child (ἦλθον περιτεμεῖν τὸ παιδίον). This circumcision, brit milah, or bris was a sign of the covenant with God that goes back to Abraham in Genesis, chapter 17:11-12. This sacerdotal covenant alliance story emphasized male circumcision as the main part of the Yahweh covenant. Thus. circumcision became a big deal. Every male was to be circumcised by removing the flesh of the foreskin of his penis, when he was eight days old. This also included male slaves born or brought into the house. An uncircumcised Jewish male would be cut off from his people, because he had broken the covenant with God. Circumcision has been practiced among many ancient and contemporary groups for either religious or hygienic reasons. In fact, despite their differences, Islamic males practice circumcision also. In the USA, most boys born in a hospital are circumcised for hygienic or health purposes.
Yahweh seemed to be against the old idea that the palace of King David was close to the Temple. Instead, he seemed to imply that there should be a separation for this new, yet unbuilt, Second Temple. Yahweh seemed upset that the old thresholds and doorposts of the Temple were right beside the royal palace. There was only a wall that separated them from his holy Temple. Thus, they defiled his holy name with all their abominations so close to his Temple, one of the main reasons for the destruction of Jerusalem. He wanted the Israelite kings to put away their idolatrous ways. Their dead bodies were to be far away from the new Temple. If they did this, Yahweh would live among them forever.
