Speak to the sons of Israel and say to them, The feasts of Jehovah, which you shall proclaim, holy convocations, even these are My appointed feasts.

These are the appointed feasts of Jehovah, holy convocations which you shall proclaim in their appointed seasons.

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

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