Charles Ellicott Commentary Isaiah 55:4

"Behold, I have given him for a witness to the peoples, a leader and commander to the peoples." — Isaiah 55:4 (ASV)

I have given him ... —Better, I gave, the words referring primarily to the historic David , though realized fully only in Him who was the faithful and true witness (John 18:37; Revelation 1:5; Revelation 3:14), the captain or leader of our salvation (Hebrews 2:10).
