This chapter speaks of the salvation of God will come and His wrath is turned away. The righteous are exhorted to follow in the steps of Abraham. Those who are running after righteousness are instructed to look to Abraham and Sarah, the rock and pit in which the house of Israel was formed, Isaiah 51:1-2. Abraham answered the call of God with obedience, Isaiah 51:2, his seed was multiplied and he was the father of the multitude, Isaiah 51:2 / Genesis 17:4-5.
Israel in captivity, her strength and number gone are to remember this. As Sarah, after a long period of barrenness gave birth to Isaac, the son of promise, so will Zion again be fruitful after a long period of desolation, Isaiah 51:3. Israel was born from the womb of Sarah but the church was born from the faith of Abraham.
Kelley, in his commentary, says the following.
‘The fact that the prophet addressed these words to them in the very land in which Abraham and Sarah had indeed received their first call gave added meaning to what is said here.’
Here we read that the certainty of the Lord’s salvation is assured and the enemies of the righteous will perish. The promise goes beyond the physical restoration of Israel, just as the promise to Abraham went beyond the material.
The world will be enlightened by the Word of God, Hebrews 1:11, and the light would be a new law that would be applicable to all the world, Isaiah 51:4 / Jeremiah 31:31-33 / Mathew 28:19-20. This salvation extends to all, Isaiah 51:5, but before the universal salvation can be offered its type must arrive.
Israel is summoned to look above, Isaiah 51:6, because of the destruction that will befall their captors, Isaiah 51:6 / Isaiah 13:6-16. The emphasis here is on the fact that God will do what He has promised to do, Isaiah 51:6.
Upon the promise of safety in the midst of destruction, Israel is instructed not to be afraid of men, Isaiah 51:7. Like the heavens and the earth, Psalms 102:26 / Isaiah 34:4 / Hebrews 1:11-12 / 2 Peter 3:10-12, men would be quickly carried away but God’s righteousness shall not be abolished, Isaiah 51:8.
Here we read Israel’s response. The exhortation of Isaiah 51:7-8, arouses a longing for salvation which brings forth this response, Isaiah 51:9. The word ‘Rahab’, Isaiah 51:9, here means Egypt, Psalms 88:8 / Psalms 89:10 / Isaiah 30:7. The king of Egypt is the monster or crocodile, as some translations render the word, which was pierced, Isaiah 51:9 / Psalms 34:13-14 / Ezekiel 29:3 / Ezekiel 32:2.
The deliverance of Israel through the Red Sea, Isaiah 51:10 / Exodus 14:21, is the literal and historical definition for these two metaphors in reference to the salvation of the saints. God’s people were ransomed from captivity Isaiah 51:10. Many Egyptians died in the Sea when they were redeemed, they were redeemed from captivity from which they couldn’t deliver themselves. Knowing that God would keep His promise, His people sing the promise, Isaiah 51:11 / Isaiah 35:10.
Jamieson, in his commentary, says the following.
‘As surely as God redeemed Israel out of Egypt, He will redeem them from Babylon, both from the literal Babylon in the age following Isaiah, and from the mystical Babylon revealed in Revelation 18:20-21, which is the last enemy of Israel and the Church, from which they have long suffered, but from which they are to be gloriously delivered.’
God now encourages Israel to believe, Isaiah 51:12. The more we understand the greatness of God, the less we will fear those who seek to oppress us, Isaiah 51:13. They are to trust in God and upon his all-sufficiency to release Israel from captivity. Cyrus loosed the people from the captivity of Babylon, Isaiah 51:14, just as the Lord Jesus Christ releases us from the captivity of sin.
Clarke, in his commentary, says the following.
‘Cyrus, if understood of the temporal redemption from the captivity of Babylon, in the spiritual sense, the Messiah, who comes to open the prison to them that are bound.’
God has pledged his absolute power to fulfil the promise, Isaiah 51:15, and now this promise reaches new glory for Israel, Isaiah 51:16.
God now cries for Israel to awake, they need to be confident because God is their help, Isaiah 51:17.
Barnes, in his commentary, says the following.
‘The common view taken of the passage is, that it means that the cup had been drunk to the dregs. All the intoxicating liquor had been poured off. They had entirely exhausted the cup of the wrath of God. Similar language occurs in Revelation 14:10.’
Jerusalem had become a drunken, Isaiah 51:17, and desperate castaway. She was completely ruined and there was none to help her, Isaiah 51:18. When they found themselves without mercy in captivity, God came for them, Isaiah 51:19.
Lowth, in his commentary, says the following.
‘Desolation by famine, and destruction by the sword, taking the terms alternately, of which there are other examples in the Bible.’
Their children fainted and lay in the street corner, absolutely helpless like antelope caught in a net, Isaiah 51:20. The antelope is among the swiftest and most graceful of animals and the spectacle of one entangled in a net is tragic and pitiful indeed. Such was the status of the Old Israel as described here. They are filled with the wrath of the LORD, with the rebuke of their God, Isaiah 51:20.
Now God’s wrath was fulfilled, Isaiah 51:21, He would take it away from Israel, Isaiah 51:22, and pour it upon her captors, Isaiah 51:23, thus, the situation is reversed. The cup was the cup of God’s wrath, Isaiah 51:22 / Jeremiah 25:15 / Jeremiah 49:12 / Jeremiah 51:7 / Lamentations 4:21 / Habakkuk 2:16 / Ezekiel 23:31-33. It was first poured out on Israel, Isaiah 51:22, now it was going to be poured out on those who persecuted His people Isaiah 51:23.
