They [the Egyptians] oppress the Israelites harshly in order to reduce their population. When their plan fails, they take more drastic measures, requiring midwives to kill babies during parturition. After this plan is aborted, the Egyptians order the liquidation of all Israelite male infants. —p.93
Bad pun, or unintentional one? Either way, it fits the Exodus story: Egypt tries to thwart YHWH's plan, but Egypt itself is thwarted. Indeed the theme of the entire Hebrew bible is the thwarting of man's and satan's plans and the fulfillment of God's.
