'Feasts of the Lord' in the Bible

"Speak to the children of Israel, and tell them, 'The set feasts of the LORD, which you shall proclaim to be holy convocations, even these are my set feasts.

"'These are the set feasts of the LORD, even holy convocations, which you shall proclaim in their appointed season.

"'These are the appointed feasts of the LORD, which you shall proclaim to be holy convocations, to offer an offering made by fire to the LORD, a burnt offering, and a meal offering, a sacrifice, and drink offerings, each on its own day;

Moses declared to the children of Israel the appointed feasts of the LORD.

Behold, I am about to build a house for the name of the LORD my God, to dedicate it to him, and to burn before him incense of sweet spices, and for the continual show bread, and for the burnt offerings morning and evening, on the Sabbaths, and on the new moons, and on the set feasts of the LORD our God. This is an ordinance forever to Israel.

and afterward the continual burnt offering, the offerings of the new moons, of all the set feasts of the LORD that were consecrated, and of everyone who willingly offered a freewill offering to the LORD.
