In Shmos6:6,7 the passuk tells us that Hashem said tell Bnei Yisroel that Vehotzeisi, Vehitzalti, Vegalti and Velakachti. The Midrash 6:4 says that there are four geulos here and that is why we drink four cups of wine. Interesting to note the Midrash does not use the word “leshonos” of geulah but rather each word on its own is a geulah by itself. The Ramban explains the difference between Vehoitzeisi and Vehitzalti that Vehotzeisi is a promise that Hashem will take us out of the land of Mitzrayim whereas the word Vehitzalti is that they will no longer be under the domain of Mitzrayim even in another place meaning they will not even have to pay taxes to them. The Ohr Hachaim Hakadosh explains this difference a little differently. Vehotzeisi will mean that they will not have such a heavy load of work it will be lighter upon them, but they would still be working a little bit for Mitzrayim as they would be scared of them. Vehitzalti means that all work will be uprooted, and they will not work or be meshubad not even one iota. Vegalti is the leaving of Mitzayim and crossing the sea. Finally, Vlakachti is where Hashem will take us as his nation and give us the Torah. 

The question is what exactly is the geulah in the fact that Velokachti, that Hashem will take us as a nation? In addition, the Passuk summarizes that after Velakachti then it says Viyedatem that I am Hashem who took you out from under the sivlos of Mitzrayim. This expression was the first word of Geulah why is it brought here again? 

Reb Yitzchok Dov Koppelman ZT”L explains that in order to understand Geulah one must understand what is Galus. We see in Parshas Vayechi the beginning of galus was that nistatmu the eyes and hearts of Bnei Yisroel the first part of the galus was a ruchniyus part of closing your ability to see you are missing something. If the Shechina lights up a person, he could be anywhere and still not be considered in galus. Once the Shechina leaves us then we are in galus and so too the Shechina is in galus. As long as Yaakov was alive Yaakov kept his eyes on us to watch that the Mitzriyim did not make us work even bfeh rach. As soon as Yaakov was niftar, Klal Yisroel dropped off a darga and they forgot who their fathers were. They became full of artziyus as the passuk says vatimolei haAretz the land became full osam they themselves were into gashmiyus. This would ne comparable to a king who had a son who was not so well behaved so he sent him away. After a few years someone was travelling to the king and offered to send the King a request from his son. The son who forgot about his father just sent a message that he needs new boots. The king upon seeing that the punishment backfired told him to come home immediately. Klal Yisroel forgot the Avos in Mitzrayim. That is why the passuk says Hashem told Moshe that he heard their screams mipnei nogsav and not because of the loss of the connection to the Avos. Hashem said he needs to take them out immediately. That is why the ultimate geulah is Velakachti that we are connected to Hashem beruchniyus. The fact the Mitzriyim had any shlita on us showed that we were not connected to Hashem that is why the passuk summarizes that you will know that Vehotzeisi which was the first step of the disconnect the Bnei Yisroel had from the Avos

Reb Yitzchok Koppelman said one more vort on this parsha when Hashem told Moshe and Aharon to speak to Bnei Yisroel and to Pharaoh the king of Mitzrayim. Rashi said that even though they are telling him about all the Makkos and punishments they will receive they still had to show him the proper respect. This proves to us that even though they were bringing upon him loads of Makkos and punishment they still had to show him respect because not showing respect to another person is worse than all the makkos one could bring on another person. 

May we all be zocheh to be redeemed from galus and to show proper respect to one another!
