Sed contra ruah (breath) meaning that people are not of concern to God before they take their first breath - "Before I formed you in the womb I knew you" (Jeremiah 1:5). So even if people were not people before they were born, God cares about them before they are people. But then we have "Who am I that the mother of my Lord should come to me?" (Luke 1:43), said to a pregnant Mary by St. Elizabeth. If Christ is fully man and Mary is already "the mother of God" when she holds Christ in her womb then people are people before they are born. So we must be misunderstanding something about what Genesis 2:7 means.

As for drinking dirty water from the floor of the temple (literally, sweep up some dust and put it in a cup with water - not an abortifacient) - the trial is asking God to reveal the truth or falsity of the woman's claim that she is virtuous (much in the same way as asking someone to take an oath in court - the bad outcome in both cases is falling under the judgement of God and receiving in some measure justice for the offense of blaspheming by asking God to witness to your lie before men).
