There are a number of celebrations found in the Hebrew Scriptures, but only three great feasts are part of the Mosaic law. They retell the story of their covenant relationship with the Lord and provide occasions to share generously with those in need. They give the people the opportunity to acknowledge publicly that He is the source of their abundance, so they won’t be tempted to think they’ve prospered on their own and forget Him.
Each of the three great celebrations are reminders of the servitude in Egypt. Passover, followed by the week of unleavened bread, is a reminder of God redeeming His people from Egypt and falls within March or April each year. The Feast of Weeks, known as Pentecost to Christians, is 50 days after firstfruits or the beginning of the barley harvest and comes in May or June. They are told to remember that they were once slaves in Egypt. The last of the great celebrations, the Feast of Shelters, comes in September or October. It is a reminder of the provision of God when the nation lived in temporary shelters while wandering in the wilderness.
9-10 Another celebration the Eternal your God wants you to have is the Feast of Weeks. Hold this celebration seven weeks after you first begin to cut and harvest the barley in your fields. Each of you will choose something to contribute out of what He has blessed you with.
