Leviticus 23:15-17

¹⁵“‘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.

¹⁶The next day after the seventh Sabbath you shall count fifty days; and you shall offer a new meal offering to the LORD.

¹⁷You shall bring out of your habitations two loaves of bread for a wave offering made of two tenths of an efah of fine flour. They shall be baked with yeast, for first fruits to the LORD.
