'First fruit' in the Bible

"Speak to the {Israelites}, and say to them, 'When you come to the land that I [am about] to give to you and you reap its harvest, then you shall bring a sheaf of the firstfruit of your harvest to the priest.

And on the first day you shall take for yourselves the first fruit of majestic trees, branches of palm trees and branches of a leafy tree and of a brook's poplar trees, and you shall rejoice {before} Yahweh your God [for] seven days.
