What does Deuteronomy 14:26 mean?

When you get there, use the money to buy whatever you want—cattle, sheep, wine, or anything else you like. Then you and your family can eat and celebrate together in God's presence. Deuteronomy 14:26 - Modern Text Bible

(The tithe money is used to buy food and drink for a joyful meal with your family before God. It's about celebration and gratitude, not just obligation.)
