(Exodus, Ibid.) "By the greatness of Your arm they were (struck) still as stone": When the Israelites emerged from the sea, the Amalekites gathered all the peoples of the world and came to fight against Israel. At that time Moses prayed, and they all were (struck) still as stone.
By the Greatness of Your Arm They Were Struck Still
Mekhilta Tractate Shirah 9:21
