He will not judge by what he sees with his eyes, or decide by what he hears with his ears; but with righteousness he will judge the needy, with justice he will give decisions for the poor of the earth. He will strike the earth with the rod of his mouth; with the breath of his lips he will slay the wicked. Righteousness will be his belt and faithfulness the sash around his waist.
This description of the future Messiah focuses on his justice. He will not go with just what he sees, or what he hears, but will seek understanding and clarity. His breath seems to refer to either his ultimate power or perhaps his teaching? "With his lips he will slay the wicked." I like to think of this as a way of pointing out how Jesus will (and did) convict others to change with his words, spoken with obvious authority. (We have just finished watching the episode of 'The Chosen' which includes the Sermon on the Mount.)
Holy Lord, you are with me always, and I am so thankful for being reminded you hear my prayers. Thank you for Jesus and his mighty teaching, which we continue to study today. May I continue to transform, Lord. Amen
