'Festival' in the Bible

They went out into the field, gathered the grapes of their vineyard and trod them, and held a festival; and they entered the house of their god, and they ate and drank, and cursed Abimelech.

David said to Jonathan, “Behold, tomorrow is the New Moon [observance], and I should sit at the table to eat [the sacrificial meal] with the king; but let me go, so that I may hide myself in the field until the third evening.

Then Jonathan said to David, “Tomorrow is the New Moon [festival], and you will be missed because your seat will be empty.

So David hid in the field; and when the New Moon [festival] came, the king sat down to eat food.

These things I [vividly] remember as I pour out my soul;How I used to go along before the great crowd of people and lead them in procession to the house of God [like a choirmaster before his singers, timing the steps to the music and the chant of the song],With the voice of joy and thanksgiving, a great crowd keeping a festival.

The Lord is God, and He has given us light [illuminating us with His grace and freedom and joy].Bind the festival sacrifices with cords to the horns of the altar.

On this mountain [Zion] the Lord of hosts will prepare a lavish banquet for all peoples [to welcome His reign on earth],A banquet of aged wines—choice pieces [flavored] with marrow,Of refined, aged wines.

What will you do on the day of the appointed festivalAnd on the day of the feast of the Lord [when you are in exile]?

saying,“When will the New Moon [festival] be overSo that we may sell grain,And the Sabbath ended so that we may open the wheat market,Making the ephah [measure] smaller and the shekel bigger [that is, selling less for a higher price]And to cheat by falsifying the scales,

Behold, I am going to rebuke your seed, and I will spread the refuse on your faces, the refuse from the festival offerings; and you will be taken away with it [in disgrace].
