Leviticus 23:13-16

Living Bible

¹³ A grain offering shall accompany it, consisting of a fifth of a bushel of finely ground flour mixed with olive oil, to be offered by fire to the Lord; this will be very pleasant to him. Also offer a drink offering consisting of three pints of wine. ¹⁴ Until this is done you must not eat any of the harvest for yourselves—neither fresh kernels nor bread nor parched grain. This is a permanent law throughout your nation.

^15-16 “The Harvest Festival (Festival of Pentecost): Fifty days later you shall bring to the Lord an offering of a sample of the new grain of your later crops.
