After Noah endured 40 days of rain, God did not speak. After the water had risen above the mountains, God did not speak. After the ark had come to a rest— after the raven, dove, and olive branch, God still did not speak.
Even on that special new year's day, when Noah took off the cover of the ark and saw the dry, but not completely dry world... even on that new year's day, which quickly turned into a new year's night, God did not speak.
As time passed, perhaps Noah grew accustomed to the silence. He had, after all, spent 120 years building the ark before he heard the voice of God again. Perhaps Noah, seeing that he and his household were still safely living in the ark, took the silence as a voiceless confirmation from God that he should continue to wait in obedience.
In the second month, on the twenty-seventh day of the month, the earth was dry. (Genesis 8:14)Almost three months had passed since that special new year's day. For just over 121 years, everything in Noah's life had been leading up to this moment: the moment that the flood was completely over— the day that God commanded him to leave the ark:
Then God spoke to Noah, saying, “Go out of the ark, you and your wife and your sons and your sons’ wives with you. Bring out with you every living thing of all flesh that is with you, birds and animals and every creeping thing that creeps on the earth, that they may breed abundantly on the earth, and be fruitful and multiply on the earth.” (Genesis 8:15-17)This was the command that Noah had been waiting so long for. Finally, after over a year of living on the ark, God broke the silence. The command had finally come, and Noah, as he had so many times before, acted in obedience (Genesis 8:18).
