'Appointed Feasts' in the Bible

Like the flock for sacrifices, like the flock at Jerusalem during her appointed feasts, so will the desolate cities be filled with flocks of people. Then they will know [with confident assurance] that I am the Lord.”’”

In a controversy they shall take their stand to act as judges; they shall judge it in accordance with My ordinances. They shall also keep My laws and My statutes in all My appointed feasts and sanctify My Sabbaths.

It shall be the prince’s responsibility to provide the burnt offerings, the grain offerings, and the drink offerings at the feasts, on the New Moons and on the Sabbaths, at all the appointed feasts of the house of Israel. He shall prepare and provide the sin offering, the grain offering, the burnt offering and the peace offerings, to make atonement for the house of Israel.”
