(Exodus 14:7) "and shalishim upon all of them": "shalishim" are warriors, as in (Ezekiel 23:23) "shalishim and notables — all riders of horses." Variantly: "and shalishim upon all of them": They were "triple ("meshulashim") -armed. R. Shimon b. Gamliel says: This refers to the third (man in the chariot). In the past there were only two charioteers. Pharaoh added a third to pursue Israel the more swiftly. Rebbi says: There were three and Solomon added a fourth.
