Exodus 10:20
But the LORD hardened Pharaoh's heart, and he would not let the Israelites go.
But the LORD hardened Pharaoh’s heart,

After Pharaoh repeatedly resisted God’s command and hardened his own heart, the Lord confirmed him in that rebellion as an act of judgment. God’s purpose was to display His power over Egypt, reveal His name among the nations, and bring Israel out by His mighty hand (Exodus 9:16). Pharaoh’s hardened heart exposed the emptiness of Egypt’s gods and the impotence of a ruler who claimed divine authority. Romans 9:17–18 recalls Pharaoh’s example to affirm God’s sovereign right to show mercy and execute judgment.

Exo 4:21 The LORD instructed Moses, “When you go back to Egypt, ……

and he would not let the Israelites go.

Pharaoh’s refusal prolonged Israel’s bondage and brought further judgment upon Egypt. Releasing the Israelites meant losing a vast labor force and yielding to the God Pharaoh had contemptuously refused to acknowledge (Exodus 5:2). Yet no earthly power could prevent the Lord from fulfilling His covenant promises to Abraham, Isaac, and Jacob. Israel’s deliverance from slavery anticipates the greater redemption accomplished by Christ, who frees His people from the bondage of sin.

Exo 7:14 Then the LORD said to Moses, “Pharaoh’s heart is unyielding;…

Now, it seems to me, that this grand quarrel of old is but a picture of God's continual contest with the powers of darkness. The mandate has gone forth to earth and hell: "Thus saith the Lord, let my people go that they may serve me." "No," saith Satan, "they shall not." And if he be compelled to yield one point, he still retains his hold upon another. If he must give way, it shall be inch by inch. Evil is hard in dying; it will not readily be overcome. But this is the demand of God, and to he last

A Poor Man's Cry, and what came of It
On this occasion I want to speak of what happens to those who do return to God; because many have newly been brought, through mighty grace. Some of them I have seen; and I have rejoiced over them with exceeding great joy. They tell me that they did distinctly lay hold on eternal life last Sabbath day; and they are clear about what it means. They came out of darkness into his marvellous light; they knew it, and could not resist the impulse at once to tell those with whom they sat in the pews, that

The Hardening in the Sacred Scripture.
"He hath hardened their heart."-- John xii. 40. The Scripture teaches positively that the hardening and "darkening of their foolish heart" is a divine, intentional act. This is plainly evident from God's charge to Moses concerning the king of Egypt: "Thou shalt speak all that I command thee; and I will harden Pharaoh's heart, and multiply My signs and wonders in the land of Egypt. But Pharaoh shall not harken unto you, and I will lay My hand upon Egypt, and the Egyptians shall know that I am the

Exposition of Chap. Iii. (ii. 28-32. )
Ver. 1. "And it shall come to pass, afterwards, I will pour out My Spirit upon all flesh; and your sons and your daughters shall prophesy; your old men shall dream dreams, and your young men shall see visions." The communication of the Spirit of God was the constant prerogative of the Covenant-people. Indeed, the very idea of such a people necessarily requires it. For the Spirit of God is the only inward bond betwixt Him and that which is created; a Covenant-people, therefore, without such an inward

Exodus
The book of Exodus--so named in the Greek version from the march of Israel out of Egypt--opens upon a scene of oppression very different from the prosperity and triumph in which Genesis had closed. Israel is being cruelly crushed by the new dynasty which has arisen in Egypt (i.) and the story of the book is the story of her redemption. Ultimately it is Israel's God that is her redeemer, but He operates largely by human means; and the first step is the preparation of a deliverer, Moses, whose parentage,
