וַיַּ֖עַשׂ נֹ֑חַ כְּכֹ֥ל אֲשֶׁר־צִוָּ֖הוּ יְהוָֽה׃
E Noé fez segundo tudo o que o SENHOR lhe ordenara.
Rashi on Genesis
ויעש נח AND NOAH DID — This refers to his coming to the Ark.
Or HaChaim on Genesis
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.
Radak on Genesis
ויעש נח, he entered the ark together with the animals slated for survival, as mentioned in ויבא נח in verse 7.
