Oh my. See, I thought meroz was a place. But the gemara Moed koton 16a says it was either a person, or sisra’s star.
See how that is. I knew the tanach, but it was worthless because I didn’t know the gemara.
At least I didn’t waste any time learning it wrong. I just remembered it from 20 or so years ago when my sister was learning some song in school for shiras devorah.
