These feasts are occasions for joy and gratitude. We are to appear before the Lord with our offerings, expressing our thankfulness for His blessings. "Rejoice before the Lord your God you and your sons and your daughters, your male and female servants, the Levites who are within your gates, and the strangers, the orphans, and the widows who are among you, at the place that the Lord your God will choose as a dwelling for his name." (Deuteronomy 16:11)
