Acts 7:7

God promised to punish the nations that oppressed Israel (Genesis 12:3) and to bring her back into the land ("this place") eventually (Genesis 15:13). God had told Moses that he would bring the Israelites out of Egypt and that they would worship Him at Mt. Sinai (Exodus 3:12). Stephen’s point was that God had promised to punish those who oppressed His people. The Jews had been oppressing the Christians by prohibiting their preaching and even flogging them (Acts 4:18; Acts 5:40). Gamaliel had warned that if the Christians were correct the Jewish leaders would be fighting against God by opposing them (Acts 5:39). God’s promise to judge His people’s oppressors went back into the Abrahamic Covenant, which the Jews treasured and Stephen reminded them of here.
