Rashi on Exodus 6:30/רש"י על שמות ו׳:ל׳

1ויאמר משה לפני ה׳ AND MOSES SAID BEFORE THE LORD — This is the statement which he made above, (v. 12), “Behold, the children of Israel have not hearkened unto me”. Scripture repeats it here, because it broke off the narrative for the reason already given. So is the method of the historian — just as a person who says, “let us return to the previous subject”.
