Shmot

When Hashem saved the Israelites and killed the Egyptians with great miracles at Yam Suf, the angels wanted to sing His praises. Hashem said to them: “The works of My Hand are drowning in the sea, and you are saying praises before Me?!” (Sanhedrin 39b). This is what Hashem said to the angels, whereas Bnei Yisrael were allowed and praised for singing to Hashem. What is the difference between them?

The pasuk in Yechezkel (16:6), which we read in the Haggada, repeats the phrase, “In your blood you shall live.” The midrash (P’sikta 17) says it refers to the blood of mila and the blood of Korban Pesach. We are forbidden to give the Korban Pesach to a non-Jew or to one who does not have a brit mila (Shemot 12:43,48). Pirkei D’Rabbi Eliezer says: “In the merit of the blood of brit mila and Korban Pesach, they were liberated from Egypt, and in the merit of the blood of brit mila and Korban Pesach, they will be liberated at the end of ‘the fourth kingdom.’”

“[Hashem] commanded [Moshe and Aharon] to Bnei Yisrael and to Paroh, King of Egypt” (Shemot 6:13). Rashi provides two explanations of what was supposed to be done in relation to Paroh. The second had to do with the various actions Hashem had spelled out. The first one is actually to treat Paroh with respect.
