Isaiah 54:3

The number of God’s people would increase, as God promised Abraham (Genesis 12:1-3; Genesis 12:7; Genesis 28:14). Future generations, from Isaiah’s perspective, would dispossess the nations (cf. the conquest of the land, Deuteronomy 9:1; Deuteronomy 11:23; Deuteronomy 12:2; Deuteronomy 31:3). Believers would take over what had belonged to unbelievers (cf. Matthew 5:5).

"Many Gentiles will undoubtedly be surprised and even chagrined to find that Israel is to have the leading place in the earth." [Note: A. Martin, Isaiah . . ., p. 102.]
