A secret revelation was made to Moses while in the presence of Pharaoh, that he might give warning of the last dreadful judgment, before he went out. This was the last day of the servitude of Israel; they were about to go away.
Their masters, who had abused them in their work, would have sent them away empty; but God provided that the labourers should not lose their hire, and ordered them to demand it now, at their departure, and it was given to them.
God will right the injured, who in humble silence commit their cause to him; and none are losers at last by patient suffering. The Lord gave them favour in the sight of the Egyptians, by making it appear how much he favoured them.
He also changed the spirit of the Egyptians toward them, and made them to be pitied of their oppressors. Those that honour God, he will honour.
