Isaiah had prophesied:

“[…] but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; he shall strike the earth with the rod of his mouth, and with the breath of his lips he shall kill the wicked. Righteousness shall be the belt around his waist, and faithfulness the belt around his loins.” Isaiah 11:4-5
“For the Lord is our judge, the Lord is our ruler, the Lord is our king; he will save us.” Isaiah 33:22
