And you shall roast it and eat it in the place the LORD your God will choose, and in the morning you shall return to your tents.
The three yearly feasts kept up communion between God and His people and preserved the face of religion in the nation. One week only was festival, yet their solemn preparation before and serious reflection afterward amounted to observance of the whole month; thus the ceremonies themselves became the means by which God's truth took root in their hearts.
