Isaías 43:3

Three names heighten God’s unique relationship to Israel, and the Exodus and Sinai experiences had taught their meaning to the people. God would even sacrifice other nations to preserve Israel for Himself. Perhaps the Lord meant that He would give Persia rulership over Egypt, Ethiopia, and Seba-as rewards for allowing the Israelites to return to their homeland. [Note: J. Martin, p. 1097.] I tend to favor this view. Another option is that He meant that He had given over Egypt and its southern extremities to redeem Israel at the Exodus. [Note: Motyer, pp. 331-32.] A third view is that these nations represent the heathen nations in general, whom God did not favor when He redeemed Israel. [Note: Young, 3:143.] In another larger sense, God sacrificed His Son as a ransom in the place of many whom He had called (cf. Isaiah 53:8-12; Matthew 20:28; 2 Corinthians 5:21).
