'Feasts of the Lord' in the Bible

Say to the children of Israel, These are the fixed feasts of the Lord, which you will keep for holy meetings: these are my feasts.

These are the fixed feasts of the Lord, the holy days of worship which you will keep at their regular times

These are the fixed feasts of the Lord, to be kept by you as holy days of worship, for making an offering by fire to the Lord; a burned offering, a meal offering, an offering of beasts, and drink offerings; every one on its special day;

And Moses made clear to the children of Israel the orders about the fixed feasts of the Lord.

See! I am building a house for the name of the Lord my God, to be made holy to him, where perfumes of sweet spices will be burned before him, and the holy bread will be placed at all times, and burned offerings will be offered morning and evening, on the Sabbaths and at the new moons, and on the regular feasts of the Lord our God. This is a law for ever to Israel.

And after that, the regular burned offering and the offerings for the new moons and all the fixed feasts of the Lord which had been made holy, and the offering of everyone who freely gave his offering to the Lord.
