As Christians, we are given a similar gift – the gift of “priesthood” as we are able to approach the throne of God through Jesus our High Priest. As priests we are to protect and keep the temple of God holy – that is, our bodies as the temple of the Holy Spirit.
When the Israelites give to God, a portion goes to the Levites. The order of giving is not Israelites > Levites > God, but Israelites > God > Levites. This mindset is important to remember for both givers (Israelites) as well as receivers (Levites). We don’t give directly to people, and we don’t receive directly from people.
And the Lord said to Aaron, “You shall have no inheritance in their land, neither shall you have any portion among them. I am your portion and your inheritance among the people of Israel. (Numbers 18:20 ESV)
To have nothing, yet everything at the same time. We used to sing this song at church, the meaning is much deeper.
