וַיַּ֖עַשׂ נֹ֑חַ כְּכֹ֥ל אֲשֶׁר־צִוָּ֖הוּ יְהוָֽה׃
노아가 여호와께서 자기에게 명하신 대로 다 준행하였더라
Ibn Ezra
Noach did all. At this point he only brought his family near to the ark but did not enter.
Or HaChaim
ויעש נח ככל אשר צוהו השם. Noach did in accordance with all that G'd commanded him. Rashi comments that this refers to his entering the ark. If that were the meaning there was no need for the Torah's comment as the Torah spells this out in 7,7 as well as 7,13.
