Isaiah 51:7

For a third time the Lord urged His people, who already knew something of righteousness, to listen to Him (cf. Isaiah 51:1; Isaiah 51:4). They were the people who had received God’s instruction by special revelation and who treasured it in their hearts. They were the godly remnant in Israel. They could count on unbelievers reproaching and reviling them. Nevertheless, they should not fear them or lose heart, but follow the example of the perfect Servant by trusting God to fulfill His Word (Isaiah 50:4-9; cf. 2 Peter 3:3-13).
