Leviticus 23:2

"These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons."

"These are the feasts of the LORD, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the LORD, a burnt offering, and a meat offering, a sacrifice, and drink offerings, every thing upon his day:"

"These things ye shall do unto the LORD in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings."

"Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God."

"I will also cause all her mirth to cease, her feast days, her new moons, and her sabbaths, and all her solemn feasts."

"Blow the trumpet in Zion, sanctify a fast, call a solemn assembly:"

"Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day."

"Look upon Zion, the city of our solemnities: thine eyes shall see Jerusalem a quiet habitation, a tabernacle that shall not be taken down; not one of the stakes thereof shall ever be removed, neither shall any of the cords thereof be broken."

"After this there was a feast of the Jews; and Jesus went up to Jerusalem."
