Kutoka 11:10

Mose na Aroni wakafanya maajabu haya yote mbele ya Farao, lakini Bwana akaufanya moyo wa Farao kuwa mgumu, wala hakuwaachia Waisraeli waondoke katika nchi yake.

And Moses and Aaron did all these wonders before Pharaoh: and the LORD hardened Pharaoh’s heart, so that he would not let the children of Israel go out of his land.
