5 You can be sure that I have heard the groans of the people of Israel, who are now slaves to the Egyptians. And I am well aware of my covenant with them. 6 "Therefore, say to the people of Israel: 'I am the Lord . I will free you from your oppression and will rescue you from your slavery in Egypt. I will redeem you with a powerful arm and great acts of judgment. 7 I will claim you as my own people, and I will be your God. Then you will know that I am the Lord your God who has freed you from your oppression in Egypt.
Matthew Henry's Commentary on Exodus 6:5-7
Commentary on Exodus 6:1-9
(Read Exodus 6:1-9)
We are most likely to prosper in attempts to glorify God, and to be useful to men, when we learn by experience that we can do nothing of ourselves; when our whole dependence is placed on him, and our only expectation is from him. Moses had been expecting what God would do; but now he shall see what he will do. God would now be known by his name Jehovah, that is, a God performing what he had promised, and finishing his own work. God intended their happiness: I will take you to me for a people, a peculiar people, and I will be to you a God. More than this we need not ask, we cannot have, to make us happy. He intended his own glory: Ye shall know that I am the Lord. These good words, and comfortable words, should have revived the drooping Israelites, and have made them forget their misery; but they were so taken up with their troubles, that they did not heed God's promises. By indulging discontent and fretfulness, we deprive ourselves of the comfort we might have, both from God's word and from his providence, and go comfortless.
