Speak to the children of Israel, and you shall say unto them, The feasts of the Lord which you shall call holy assemblies, these are My feasts.

These [are] the feasts to the Lord, holy convocations, which you shall call in their seasons.

Three times in the year shall all your males appear before the Lord your God in the place which the Lord shall choose in the Feast of Unleavened Bread, and in the Feast of Weeks, and in the Feast of Tabernacles: you shall not appear before the Lord your God empty.

Each one according to his ability, according to the blessing of the Lord your God, which He has given you.

To everything there is a season, and a time for every purpose under heaven.
