In the context of the agricultural imagery used throughout God's Word, the barley harvest holds significant meaning as it relates to the spiritual harvest of God's children. The Feast of Firstfruits, known as the day of the wavesheaf, marked the beginning of the grain harvest when the firstfruits of the barley were offered before the Lord. This early harvest, paralleling Israel's spring grain harvest, symbolizes the initial gathering of God's chosen ones. In ancient times, harvesting barley was a meticulous process, unlike modern methods. The grain had to be cut before it was fully ripe to prevent it from falling out of the husk prematurely. At the stage when the grain was white, transitioning between immature green and fully ripe golden brown, reapers used sharp sickles to cut the standing grain. Determining the right time to cut was critical; too early meant immature grain, and too late risked losing the harvest. After cutting, the stalks were gathered into sheaves, tied together, and stood upright in shocks, resembling a cone shape. These shocks, consisting of 15 to 20 sheaves, allowed air to pass through, enabling the grain to mature and dry while protecting it from ground moisture and rot. Scattered across the field, the shocks stood for many days until the grain was ready for threshing. Once ready, the shocks were hauled to the threshing floor where the grain was separated from the husks through shaking or gentle beating. The final step, winnowing, involved throwing the grain into the air on a breezy day to remove any remaining chaff, leaving only clean, usable grain. This detailed process of barley harvesting in ancient times provides a vivid analogy for the careful and staged gathering of God's firstfruits, reflecting the patience and precision required in the spiritual harvest.

Wavesheaf Day marked the beginning of the harvest. The waving of the sheaf was a critical day when the harvest began, and thus it was a common work day, not a holy day. God told Israel to begin to count the seven weeks from the time of putting the sickle to the grain. None of the groups at the time of Christ put the beginning of the harvest on a day about which God said no customary work should be done. All the Jewish groups steered clear of starting the harvest and the corresponding count on an annual Sabbath. The Israelites could not offer grain that came from a foreigner's hand because God would not accept offerings of grain that the Israelites did not sow. The only grain available in the first year was not from their own labors.

Wavesheaf day centers on the barley harvest. Wavesheaf day marks the start of reaping what an individual has sown by his own hand in the land. The first record of sowing and reaping by one of God's people in the promised land appears when Isaac sowed and reaped with abundant blessing from God. That example establishes the principle that the grain must come from the labors of God's people rather than from foreigners. Hundreds of thousands of Israelites brought sheaves of barley as their firstfruits offering on Wavesheaf day. Each person cut a sheaf from his own harvest on that day. The Wavesheaf offering then came from that harvest. Wavesheaf day therefore concerns the harvest itself before any offering takes place. The underlying harvest and the Wavesheaf offering remain linked. This linkage keeps Wavesheaf day from coinciding with the first day of Unleavened Bread.
