He turned their heart to hate his people,.... Whom before they loved and esteemed: when Pharaoh and his servants heard of Joseph's father and brethren, they were greatly pleased, and invited them into Egypt; and, when come, placed them in the land of Goshen; but when a new king arose, and a new generation, which knew not Joseph, the hearts of these were turned to hate them.
This is said to be of the Lord: not that he put any hatred into them, there was no need of that; there is enough of that naturally in every man's heart against good men, and all that is good: but he did not restrain that hatred, as he could have done, but suffered them to let it have vent; and moreover, he did those things which were an occasion of it, and which served to stir up their hatred; as increasing their numbers, and making them stronger and mightier than they, Ex 1:9.
To deal subtilly with his servants; by putting them to hard labour, and using them with great rigour, in order to weaken their strength; by commanding the midwives to kill every son that was born; and by publishing an edict, to cast every male child into the river and drown it, and so hinder the increase of them.
