And Noah builded an altar unto the Lord; and took of every clean beast and of every clean fowl, and offered burnt offerings on the altar. Noah's first act after leaving the ark of deliverance was an act of worship. He built an altar, a place of slaying the sacrificial victim, and brought a sacrifice of thanksgiving to God. That is a proof of true faith, of true piety, if men wait for the help of the Lord in all patience, even when deliverance seems long in coming, and finally give all praise and thanks to God for the revelation of His goodness in sending help.
