Hadrash V'HaIyun on Parashas Vaera: translation request

Question

In sefer Hadrash V'HaIyun, Rabbi Aharon Levin comments on Parashas Vaera. However, I am not able to understand these concepts. Can somebody maybe translate it, maybe that would help me in getting understanding of it.

Rabbi Levin discusses the idea that a prophet can give different messages upon people.

Message 1: this is given upon a sinful nation. The prophecy deals with bitter visions and tribulations that will befall a sinful nation.

Message 2: this is given to a nation that is in distress and wants to walk in Hashem's ways. When a nation is in distress, Hashem will appear and tell them that their future will be bright.

I suppose Rabbi Levin is connecting message 2 to this week's parasha (Vaera). That G-d promises Moshe Rabbeinu that He will take B'nei Yisrael out of Mitzrayim, free them, make them unto a nation etc...

Furthermore, Rabbi Levin discuss the idea that G-d put Moshe Rabbeinu in charge of this special mission. He says something like "these two concepts, e.g. walking and have a mission are united with each other".

The above is stated on this page.

Answer 1

He's saying that Hashem sends prophets for two reasons: either to bear good tidings or warnings of punishment. The former Hashem calls שליחות; the latter, הליכה, as though to distance Himself from the assignment.

That's why, in Yeshayahu 6:8, when Hashem wants to reveal both the troubles that will befall the Jews as well as the news of their ultimate redemption, He asks את מי אשלח ומי ילך לנו, but Yeshayahu only responds הנני שלחני, because he only wanted to be an agent for good news.

Moshe also had both jobs: On the hand, he was sent to redeem the Jews from slavery; on the other, he was an agent of retribution against the Egyptians, as hinted in the dual language of Shmos 3:10, ועתה לכה ואשלחך. But Moshe also wasn't happy about being an agent of retribution. And once his talk with Pharaoh backfired on the Jews, Moshe additionally felt justified in complaining to Hashem (Shmos 5:22) למה זה שלחתני. As Rashi explains, וא"ת מה איכפת לך קובל אני על ששלחתני, meaning, "Even though it's not my place to question Your decision, how can this be called שליחות? Where's the good news?"

Hashem's response, as explained in Rashi (Vaera 6:2), addresses both points. On the issue of הליכה, there's no reason to be reluctant because that mission comes with a great reward too: נאמן לשלם שכר טוב למתהלכים לפני. On the question of שליחות, have a little patience; it is indeed a mission of good which will ultimately benefit the Jews, fulfilling the promise made to your forefathers: לא לחינם שלחתיך כי אם לקיים דברי שדיברתי לאבות הראשונים.
