'Festivals' in the Bible

and to offer all burnt offerings to the Lord, on the sabbaths, the new moons and the fixed festivals in the number set by the ordinance concerning them, continually before the Lord.

He also appointed the king’s portion of his goods for the burnt offerings, namely, for the morning and evening burnt offerings, and the burnt offerings for the sabbaths and for the new moons and for the fixed festivals, as it is written in the law of the Lord.

and afterward there was a continual burnt offering, also for the new moons and for all the fixed festivals of the Lord that were consecrated, and from everyone who offered a freewill offering to the Lord.

“I hate your new moon festivals and your appointed feasts,They have become a burden to Me;I am weary of bearing them.

“At the festivals and the appointed feasts the grain offering shall be an ephah with a bull and an ephah with a ram, and with the lambs as much as one is able to give, and a hin of oil with an ephah.

“I hate, I reject your festivals,Nor do I delight in your solemn assemblies.

“Then I will turn your festivals into mourningAnd all your songs into lamentation;And I will bring sackcloth on everyone’s loinsAnd baldness on every head.And I will make it like a time of mourning for an only son,And the end of it will be like a bitter day.
