Genesis 21:10-12

21:10 So she said to Abraham, “Banish that slave woman and her son, for the son of that slave woman will not be an heir along with my son Isaac!”

21:11 Sarah’s demand displeased Abraham greatly because Ishmael was his son. 21:12 But God said to Abraham, “Do not be upset about the boy or your slave wife. Do all that Sarah is telling you because through Isaac your descendants will be counted.

Romans 11:7-11

11:7 What then? Israel failed to obtain what it was diligently seeking, but the elect obtained it. The rest were hardened, 11:8 as it is written,

“God gave them a spirit of stupor,

eyes that would not see and ears that would not hear,

to this very day.”

11:9 And David says,

“Let their table become a snare and trap,

a stumbling block and a retribution for them;

11:10 let their eyes be darkened so that they may not see,

and make their backs bend continually.”

11:11 I ask then, they did not stumble into an irrevocable fall, did they? Absolutely not! But by their transgression salvation has come to the Gentiles, to make Israel jealous.
