“Speak to the children of Israel and say to them, ‘The appointed times (established feasts) of the Lord which you shall proclaim as holy convocations—My appointed times are these:

‘These are the appointed times of the Lord, holy convocations which you shall proclaim at their appointed times:

‘These are the appointed times (established feasts) of the Lord, which you shall proclaim to be holy convocations, to present an offering by fire to the Lord, a burnt offering and a grain offering, sacrifices and drink offerings, each on its own day.

So Moses declared to the Israelites the appointed feasts of the Lord.
