What does the Bible say about God's ordination?

In the Scriptures, ordination refers to God's sovereign setting apart of individuals for specific tasks. For instance, in Zechariah 3, Joshua, the high priest, is depicted as being charged by the angel of the Lord. This charge reflects God's sovereign decision to cleanse him of his iniquities and appoint him to serve in His house. This concept of being 'set apart' is instrumental throughout the Bible, illustrating that God's choices and purposes are established before the foundation of the world, as seen in Christ's eternal role as Savior in the covenant of grace.
