First Fruits

"When they went into the land, the land that was promised to Abraham, Isaac and Jacob’s seed; they found houses, wells, vineyards, milk and honey as a inheritance for them and their children. All of which they never sowed, but will reap; nor built, but will occupy. 
Likewise we as they are commanded to feast unto YeHoVaH, at the appointed time because he gave us this freedom, land, property and promise of inheritance and as a result we like them shall not come before him empty.
It is an act of obedience and faith to give back to YeHoVaH, as you believe he will continue to prosper and be your provision, so you lack no good thing."
