'Sheaf' 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 he shall wave the sheaf {before} Yahweh for your acceptance; the priest shall wave it {on the day after} the Sabbath.

And on the day of your waving the sheaf you shall {offer} a {yearling} male lamb without defect as a burnt offering to Yahweh.

" 'And you shall count for yourselves {from the day after} the Sabbath, from the day of your bringing the wave offering's sheaf--[there] shall be seven full weeks.
