Under the Law of Moses, the Israelites could make different kinds of offerings to the Lord, including the grain offering,

“If your offering is a grain offering baked in a covered pan, it shall be made of fine flour with oil. You shall bring the grain offering that is made of these things to the Lord. And when it is presented to the priest, he shall bring it to the altar. Then the priest shall take from the grain offering a memorial portion, and burn it on the altar. It is an offering made by fire, a sweet aroma to the Lord. And what is left of the grain offering shall be Aaron’s and his sons’. It is most holy of the offerings to the Lord made by fire” (Leviticus 2:7–10).

Likewise, what we give every first day of the week for the church treasury is not the only sacrifice that we can make to the Lord today, but we can praise Him with our lips (Hebrews 13:15), we can support missionaries—although not to the detriment of our home congregation (Philippians 4:8), and many other things.
