The slavery of Mitzrayim (Egypt) and the Exodus is both the history of the nation of Yisrael (Israel) and also a prophetic picture of the redemption that HaShem is bringing about in the Earth through Zero’o (His Arm).
It concerns all nations—anyone who fears HaShem and seeks His mercy—even as it was a mixed multitude that left Mitzrayim (cf. Shemot / Exodus 12:38). Just as those who were not native born in Yisrael were joined to them through Moshe (Moses) at that time, those who leave the ways of this world behind them to follow Yeshua are likewise joined to HaShem and grafted into the commonwealth of Yisrael (cf. Zechariah 2:10-11, Romans 11:11-24, Ephesians 2:11-22).
Although all people today are the descendants of Noakh (Noah), who found favour in the eyes of HaShem, because of the idolatrous rebellion of the nations against their Creator, the eyes of the peoples have been darkened.
As Shaul says in his letter to the Romans,
‘For although they knew the G-d, they did not honor Him as G-d or give thanks to Him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal G-d for images resembling mortal man and birds and animals and creeping things. … And since they did not see fit to acknowledge the G-d, the G-d gave them up to a debased mind to do what ought not to be done. They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips, slanderers, haters of G-d, insolent, haughty, boastful, inventors of evil, disobedient to parents, foolish, faithless, heartless, ruthless.’
— Romans 1:21-23,28-31
The future is bleak for those who are enslaved in such ways, but there is hope for those who humble themselves before HaShem by faith in His Messiah, even as there was for the mixed multitude that left Mitzrayim. HaShem will deliver them from slavery through Zeroa HaShem.
While the Universe was made through Zeroa HaShem, as Yirmeyahu says, the first time he is referred to in the Jewish Scriptures by this name is in the Torah (Law) of Moshe (Moses), in Shemot (Exodus), when HaShem commissioned His servant Moshe to speak words of salvation to his people; the promise of deliverance from the slavery of Mitzrayim.
HaShem said to Moshe,
‘Say therefore to the Children of Yisrael, ‘I am HaShem, and I will bring you out from under the burdens of Mitzrayim, and I will rid you of their bondage, and I will redeem you Bizroa Netuyah [with an Outstretched Arm], and with great judgements… ”
— Shemot 6:6
This great salvation was as much a deliverance from spiritual darkness as it was a physical deliverance from the oppressive slavery of Mitzrayim, foreshadowing the ultimate spiritual emancipation yet to come.
Yekhezkel HaNavi (the Prophet Ezekiel) records,
‘Thus says the Lord HaShem: ‘On the day when I chose Yisrael, I lifted My Hand to the offspring of the house of Ya’akov, making myself known to them in the land of Mitzrayim. I swore to them, saying, ‘I am HaShem your G-d’. On that day, I swore to them that I would bring them out of the land of Mitzrayim into a land that I had searched out for them, a land flowing with milk and honey; the most glorious of all lands. And I said to them, ‘Cast away the detestable things your eyes feast on, every one of you, and do not defile yourselves with the idols of Mitzrayim. I am HaShem your G-d.”
— Yekhezkel (Ezekiel) 20:5-8a
HaShem did just what He had said. With great acts of judgement on Mitzrayim and its false gods (cf. Numbers 33:4), HaShem delivered His people from slavery by Zeroav HaNetuyah (His Outstretched Arm). In the final judgement inflicted on Pharoah and his army, HaShem parted Yam Suf (the Reed Sea, a.k.a. Red Sea) and made the Sea a way for His people to pass over, while destroying the enemies of His people in the same waters.
Looking forward to the final redemption, which is yet to come, Yeshayahu HaNavi (the Prophet Isaiah) tells us that it was Zeroa HaShem who parted Yam Suf (the Reed Sea).
‘Awake, awake, put on strength, Zeroa HaShem… Was it not you who dried up the Sea, the waters of the great deep, who made the depths of the Sea a way for the ransomed to pass over?’
— Yeshayahu 51:9b,10
After crossing Yam Suf, having seen the Egyptians dead on the seashore, Moshe and the Children of Yisrael sang the following both in retrospect and prophetically.
‘You have led in Your mercy the people whom You have redeemed. You have guided them in Your strength to Your holy habitation. The peoples shall hear and tremble; anguish shall take hold of the inhabitants of Pelashet [Philistia]. The chiefs of Edom shall be terrified. Trembling shall take hold of the mighty men of Moav. All the inhabitants of Kena’an melt away; fear and dread shall fall upon them. Because of the greatness of Zeroakh [Your Arm], they shall be as still as a stone; until Your people pass over, HaShem, till the people whom You have purchased pass over. You shall bring them in and implant them in the mountain of Your inheritance, in the place, HaShem, which You have made for Your abode; in the Sanctuary, HaShem, which Your hands have established. HaShem shall reign to the World to Come and forever.’
— Shemot 15:13-18
So it is that the Children of Yisrael are commanded,
‘You shall therefore love HaShem your G-d, and keep His charge, His statutes, His judgments, and His commandments, all the days. And let it be known to you today, for I am not speaking with your children who have not known or seen the discipline of HaShem your G-d, His greatness, His Mighty Hand, and Zeroav HaNetuyah [His Outstretched Arm]…’
— Devarim (Deuteronomy) 11:1-2
