Leviticus 12:2

Then when the days of their purification according to the law of Moses were completed [Note: This was a set procedure required for a Jewish mother on the birth of a child. See Lev. 12:1-8], Joseph and Mary brought Jesus up to Jerusalem to present Him to the Lord.

Therefore, just as sin came into the world through [the action of] one man [i.e., Adam] and [physical] death through that sin, so [physical] death has spread to all people, because all people have sinned. [Note: This difficult passage (verses 12-21) seems to be saying that the entire human race must experience physical death because of Adam's sin (I Cor. 5:22), which is somehow considered to be everyone's sin. See Murray, pp. 180-187, for a thorough discussion].
