'Festival' in the Bible

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

All the people went away to eat, to drink, to send portions and to celebrate a great festival, because they understood the words which had been made known to them.

These things I remember and I pour out my soul within me.For I used to go along with the throng and lead them in procession to the house of God,With the voice of joy and thanksgiving, a multitude keeping festival.

The Lord is God, and He has given us light;Bind the festival sacrifice with cords to the horns of the altar.

You will have songs as in the night when you keep the festival,And gladness of heart as when one marches to the sound of the flute,To go to the mountain of the Lord, to the Rock of Israel.

What will you do on the day of the appointed festivalAnd on the day of the feast of the Lord?

But I have been the Lord your God since the land of Egypt;I will make you live in tents again,As in the days of the appointed festival.
