Who sent tokens and wonders into the midst of thee, O Egypt, upon Pharaoh, and upon all his servants.
Who sent tokens and wonders into the midst of thee, O Egypt. The phrase is moulded after Psalms 116:19. The allusion is to the plagues sent before that on the first-born (Psalms 135:8). Compare Exodus 15:7, "thou sentest forth thy wrath" etc.
