Aside from their regular offerings for sin, Israel’s worship included returning to Yahweh a tenth part of all their increase. This meant that a tenth of the best of the flock or field was to be given up as proof of one’s faith in Almighty Yahweh as Provider of everything. The principle of giving back through various sacrifices was at the core of the many offerings that Yahweh expected of Israel each day, and it remains a key part of New Testament worship.
