The answer is: Meat and grain

Lev 7:30, 23:17 - The wave offering was part of the peace offerings given to God.

The wave offering is such an intriguing element of ancient Israelite rituals! Picture this: during the celebrations, folks would present their offerings—meat and grain—in a wave-like motion before God. It's almost like a divine dance of gratitude! The ritual, steeped in communal spirit, had both practical and symbolic meanings.

In Leviticus, specifically chapter 7 and 23, we see how crucial these offerings were to the community's relationship with God. They weren't just about following rules; they embodied joy and repercussion, serving as a celebration of peace. Isn't it fascinating that this practice was designed to reinforce cohesion within the community while acknowledging the divine?

Fun trivia for you: the grain used for such offerings was likely made from barley or wheat, staples in the ancient agrarian society of Israel. Meanwhile, the flesh from specific types of animals, typically from the herd or flock, emphasized ritual purity and the idea that only the best should be offered to God.

One noteworthy echo in the scriptures is how these wave offerings foreshadow later traditions, like the practices of communal potlucks shared in vineyards or among families, reminiscent of the New Testament where fellowship and sharing occupy a pivotal role. It beautifully illustrates how a simple act of giving morphs into a profound communal bond with both God and humanity. The wave offering highlights the richer texture of worship—a blend of sacrifice, celebration, and togetherness.
