Prayer beads are commonly found in various religions as a tool for meditation and prayer. Did Judaism ever have any religious use of prayer beads, perhaps among the Jewish Sages? Or would this be considered halachically forbidden as a form of idolatry?
I don't know how else to answer this question but the answer is that beads have never played a part in Jewish worship. It's simply not the way that our prayers have been formatted. We don't need to "count" prayers like Catholics with rosary beads or the like.
