Deuteronomy 26 is a chapter that outlines the instructions for the Israelites when they enter the Promised Land. It begins with the Israelites being instructed to take the first fruits of the land and bring them to the Lord as an offering. This offering is to be accompanied by a declaration of gratitude for the Lord's faithfulness in bringing them to the land. The Israelites are then instructed to tithe a tenth of their produce to the Lord, and to remember the Lord's faithfulness in delivering them from slavery in Egypt.
The chapter then goes on to outline the laws of the land, including the laws of inheritance, the laws of the Sabbath, and the laws of the festivals. The chapter also outlines the punishments for those who break the laws, and the rewards for those who obey them.
Finally, the chapter ends with a reminder to the Israelites to remember the Lord's faithfulness in bringing them to the land, and to be obedient to His commands. This is a reminder to the Israelites to remain faithful to the Lord and to His laws, and to be thankful for the blessings He has bestowed upon them.
