Verses 7 and 12–“And the children of Israel were fruitful, and increased abundantly, and multiplied, and waxed exceeding mighty; and the land was filled with them… But the more they afflicted them, the more they multiplied and grew. And they were grieved because of the children of Israel.”
This is proof that God watches over his people in a time of trouble, in a time when Satan is against them, in the very time that the children of this world would persecute them and hope for their destruction. God is able to use our time of trouble for His own glory.
