Leviticus 23
14 Ref You shall eat neither bread, nor roasted grain, nor fresh grain, until this same day, until you have brought the offering of your God. This is a statute forever throughout your generations in all your dwellings.
15 Ref "'You shall count from the next day after the Sabbath, from the day that you brought the sheaf of the wave offering; seven Sabbaths shall be completed:
16 Ref even to the next day after the seventh Sabbath you shall number fifty days; and you shall offer a new meal offering to Yahweh.
17 Ref You shall bring out of your habitations two wave-loaves of two tenth parts of an ephah: they shall be of fine flour, they shall be baked with yeast, for first fruits to Yahweh.
