Ye are my witnesses, salth the Lord (Isa. 43:10)
This is a major theme for this prophet. As beneficiaries of God's marvelous deliverance from Egypt, from famine, pestilence, war, and so forth, the people of Israel were qualified to bear witness to the presence, power, and nature of God. In the tradition of Old Testament (OT) justice, there was an obligation to testify to known facts (see Lev. 5:1), and therefore this statement is also a charge to perform the required service.
