Rashi on Exodus 12:31/רש"י על שמות י״ב:ל״א

1ויקרא למשה ולאהרן לילה AND HE CALLED FOR MOSES AND AARON BY NIGHT — This tells us that he went round to the entrances leading into the city (i. e. to each different district) crying out, “Where does Moses reside? Where does Aaron reside?” (Mekhilta).

2גם אתם BOTH YE — the men,

3גם בני ישראל AND THE CHILDREN OF ISRAEL — the little ones (i. e. בני must be understood literally).

4ולכו עבדו את ה' כדברכם AND GO, SERVE THE LORD, AS YE HAVE SAID — everything shall be as you have said and not as I have said: annulled is what I have said, (5:2) “I will not let you go” (“Arise, go out”); annulled is, (10:8) “who are they that shall go?” (“go, both you and the children of Israel”); annulled is, (10:24) “but your flocks and herds must remain” (“Take also your flocks and herds”) (cf. Mekhilta).
