May the Lord bless you and protect you. May the Lord smile on you and be gracious to you. May the Lord show you His favor and give you His peace.
Then God makes a promise in verse 27 that whenever Aaron and his sons bless the people of Israel in His name, the Lord Himself will bless them! I believe this is a promise that God continues to honor for all of His children, so it’s important for us to pray blessing prayers over people in the Lord’s name.
Then there’s a great prayer for blessing others with spiritual growth in the Lord from Ephesians 3:16-20:
16 I pray that from his glorious, unlimited resources he will empower you with inner strength through his Spirit. 17 Then Christ will make his home in your hearts as you trust in him. Your roots will grow down into God’s love and keep you strong. 18 And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is. 19 May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God.
20 Now all glory to God, who is able, through his mighty power at work within us, to accomplish infinitely more than we might ask or think.
