Exodus 34:22-24

Revised Standard Version Catholic Edition

²² And you shall observe the feast of weeks, the first fruits of wheat harvest, and the feast of ingathering at the year’s end. ²³ Three times in the year shall all your males appear before the Lord God, the God of Israel. ²⁴ For I will cast out nations before you, and enlarge your borders; neither shall any man desire your land, when you go up to appear before the Lord your God three times in the year.
