Isaiah 42:10-12

A new song arises in Scripture when someone has learned of something powerful and good that God has done or will do (cf. ch. 12; Psalms 33:3; Psalms 40:3; Psalms 96:1; Psalms 98:1; Psalms 144:9; Revelation 5:9; Revelation 14:3). Here it is salvation through the Servant that prompts this song of praise (cf. Isaiah 6:3). Isaiah called on everyone to praise the Lord because the Servant’s ministry would benefit the whole earth. People living on the farthest seacoasts and in the desert lands should praise Him. Kedar, a son of Ishmael (Genesis 25:13), was also the name of a town in the Arabian Desert (cf. Isaiah 21:16-17; Isaiah 60:7). Sela was near modern Petra and was the mountain fortress city of Edom (cf. Isaiah 16:1). These people in various places represent diverse sources from which universal praise should come to the Lord.
