Moses
Genesis 6:22BSB·traditional attribution

So Noah did everything precisely as God had commanded him.

John Calvin Reformed @genevareformer

22. Thus did Noah . In a few words, but with great sublimity, Moses here commends the faith of Noah. The unskilful wonder that the apostle (Hebrews 11:7) makes him “heir of the righteousness which is by faith.” As if, truly, all the virtues, and whatsoever else was worthy of praise in this holy man, had not sprung from this fountain.

Matthew Henry Presbyterian @wholebiblehenry

Noah's care and diligence in building the ark may be considered, 1. As an effect of his faith in the word of God. God had told him he would shortly drown the world; he believed it, feared the threatened deluge, and, in that fear, prepared the ark.

Jamieson-Fausset-Brown Reformed @jfbcommentary

Thus did Noah--He began without delay to prepare the colossal fabric, and in every step of his progress faithfully followed the divine directions he had received. Next: Genesis Chapter 7
