5 I have also heard the groaning of the Israelites whom the Egyptians are holding as slaves, and I have remembered my covenant. 6 Say therefore to the Israelites, "I am the Lord, and I will free you from the burdens of the Egyptians and deliver you from slavery to them. I will redeem you with an outstretched arm and with mighty acts of judgment. 7 I will take you as my people, and I will be your God. You shall know that I am the Lord your God, who has freed you from the burdens of the Egyptians.
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.
