In Biblical times, the concept of giving someone a blessing was a big deal. When it was God doing the blessing, it was God showing his special favor. When it was one person, like Abraham blessing Isaac, or Isaac blessing Jacob, it was that person calling down God’s favor on the one he was blessing.
In Numbers 6:22-27 God tells Moses how Aaron is to bless his people and why. The Living Bible translates it like this “Now the Lord said to Moses, “Tell Aaron and his sons that they are to give this special blessing to the people of Israel: ‘May the Lord bless and protect you; may the Lord’s face radiate with joy because of you; may he be gracious to you, show you his favor, and give you his peace.’ This is how Aaron and his sons shall call down my blessings upon the people of Israel; and I myself will personally bless them.”
There are many different translations of this passage, and all get the message across, that God wants to protect us and show us his favor. He wants to be happy with us, and he wants us to have the peace that comes from trusting him.
In modern times the pastor in our Church will say this blessing, just like Aaron, calling down God’s blessings on us. It is always a comforting part of a service. When we tell someone “God Bless,” we are doing the same, asking for God to show them his favor and peace.
Dear Lord, We thank you for your blessing and for the guidance you gave us through this story of Moses and Aaron. Bless those we love, and help us make a point of asking for your blessing on them when we see them. In Jesus’ name we pray. Amen.
