"magic judgment" is unnecessarily cynical. if the abortion happens successfully the baby was illegitimate, and if not the baby is totally legitimate. it's obviously designed to save face.
Numbers 5:16-28. 5:21 is the line that proves that the ceremony is an abortion, since the drink causes the abdomen to swell and a miscarriage to occur. It's an attempt to cut away the chaff of the surrounding text while still giving the passage that demonstrates the abortion within the text.
It’s the whole section, 11-29. 21 is the passage which describes the outcome. If you read the whole section it’s a pretty clear set of steps on how to abort a fetus.
Granted, it requires the Lord. If you don’t believe we cannot help you.
You have to do a little more research than that for this to make sense. You're right, this is inaccurate. But, being curious, I checked the rest of the chapter. See my other post in this thread.
