1 Chronicles 22:11

The Lord be with thee. — See 1 Chronicles 9:20. (1 Samuel 3:19; 2 Kings 18:7 : “The Lord was with him.”) The phrase is the origin of the familiar liturgical formula, “The Lord be with you.”

And prosper thou, and build the house. — Not a command, but a wish, i.e., mayest thou prosper and build. The verb “prosper” (literally, carry through, make succeed) is used transitively in 2 Chronicles 7:11 and Genesis 24:40.

As he hath said of (upon) thee. — This phrase (dibbèr ‘al) is specially used of Divine threats and promises. (See Genesis 18:19; Isaiah 37:22; and comp. 1 Chronicles 22:8, above: “And the word of the Lord became upon me.”)
