Isaiah 50:10

The Lord (Isaiah 50:11) now addressed the Israelites through Isaiah again (cf. Isaiah 50:1). He picked up the "whos" from Isaiah 50:8-9 and asked who among His people feared the Lord and obeyed the instruction of the Servant. Fearing the Lord and obeying the Servant are synonymous. The Israelites too, like the Servant, were walking in darkness, not the darkness of sin but the darkness of being called by God to a mission that involved suffering and misunderstanding (cf. Isaiah 50:6; Isaiah 42:6; Exodus 19:4). Such a people should trust in the reputation and character of the Lord, and rely on Him, like the Servant (cf. Isaiah 50:7-9; Colossians 2:4-7).
