'Festival' in the Bible

" 'Surely on the fifteenth day of the seventh month, at your gathering the land's produce, you shall hold Yahweh's festival for seven days; on the first day [there shall be] a rest period and on the eighth day a rest period.

And you must hold it [as] a festival for Yahweh [for] seven days in the year; [it shall be] a {lasting statute} throughout your generations; in the seventh month you must hold it.
