I have heard someone identifying as a Christian argue that the process in Numbers 5 supports abortion since a woman suspected of being unfaithful to her husband involves an induced miscarriage/abortion if she is unfaithful, and that verse 27 demonstrates this. The verse says that if the woman is guilty, her thigh will rot, which is interpreted as a miscarriage by some and merely the inability to conceive by others.
Does this verse involve an abortion? And even if so, is it what the woman drinks that causes it, or is it G-d who causes it?
Note: I'm not asking whether abortion is right or wrong but merely whether this verse addresses the issue in any form.
