“Behold, the days come, saith the LORD, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth.”
King James Version (KJV)
23:5 Behold - Even the Jewish doctors, as well as the Christian interpreters, understand this as a prophecy of the Messiah who is called the branch, #Isa 4:2 53:2|. And here, he is called the righteous branch, not only because himself was righteous, but because he maketh his people righteous. Shall execute - Protecting the innocent, and defending his people throughout the world, judging the prince of the world, and by his spirit governing his people.
