Lapidation is another word for stoning, like when convicted law violators were stoned as punishment (usually for adultery). Today, getting stoned has a totally different meaning. [I love finding new obscure words, so when I’m sitting in my recliner listening to music with headphones on (no ear-buds for me), drawing in a sketchbook and writing blog posts, and The Wife asks me, “Are you stoned again?” I can reply, “Why no sweetheart, just a little lapidated”.]
Stoning was a pretty harsh punishment, especially for one who was a probation officer for thirty years; we only got to throw ‘the book’ at people. Stoning was a community event. Everybody got to participate. That way no one individual took the blame for the killing. “Hey, I only threw a rock”, was a common rejoinder. Jesus allowed only those who were without blame to throw the first stone. Guess ya had to be someone very special to go to the front of the line. Being first isn’t that big a deal anyway. it’s the last guy (or gal) who casts the final stone that really counts. Kinda like being the straw that broke the camel’s back except a lot heavier. The first ‘caster’ probably isn’t gonna do much damage, unless he’s a good shot. It’s the last guy who gets to teach the adulterer a lesson they’ll never forget. The first shall be last, and the last shall be first!
