You non-Jews who trust in Jesus must not despise the Jews whom God has rejected. You must not become proud, but instead beware. God will not spare you if you fall away from him, and he will certainly act kindly toward the Jews if they trust in Christ.

Romans 11:17-24

17 God has rejected many of the Jews [MET], like branches of a tree are broken off {like people break off dead branches of a tree}. And each of you non-Jews whom God has accepted is like [MET] a branch of a wild/uncultivated olive tree that was {that someone} grafted among the branches (OR, onto one of the branches) that were left on a cultivated olive tree. God has caused you to benefit from how he blessed our(exc) first Jewish ancestors, as branches benefit from the nutritious sap from the roots of a cultivated olive tree [MET]. 18 However, you non-Jews must not despise the Jews whom God rejected [MET], who are like the branches that were broken off from the tree If any of you wants to boast about having received blessings from God, remember this: Branches do not nourish the roots. Instead the roots nourish the branches [MET]. Similarly, you are blessed by God because of what you have received from the Jews! It is not what the Jews have received from you that blesses them [MET]! 19 If one of you then says, “God rejected the Jews [MET] like branches [MET] that are broken {that people broke} off a tree and rejected, in order that he might accept us non-Jews, as branches [MET] of a tree are grafted in {as people graft in branches of a tree},” 20 I would reply that this is true. However, it is because the Jews did not believe in Christ that they were rejected [MET] {that God rejected [MET] them}. As for you, it is only because you believe in Christ that God has accepted you! So do not any of you become proud, but instead beware of what could happen to you 21 Since God did not spare the unbelieving Jews [MET] who were like a tree’s natural branches, he will not spare any of you if you do not keep trusting in him!

22 Note then, that God acts kindly, but he also acts severely. He has acted severely toward the Jews who have stopped trusting in him. On the other hand, he acts kindly toward each of you non-Jews only if you continue to appreciate his acting kindly toward you. However, you will be rejected {he will reject you} if you do not keep trusting in him. 23 And if the Jews believe in Christ [LIT], God also will reunite them to himself as branches are grafted {as people graft branches} into a tree again, because God is able to do that. 24 Each of you non-Jews who were previously separated from God has benefited from the ways in which God blessed the Jews [MET]. That is like taking branches that have been cut {that someone has cut} from a wild olive tree that just grew without being planted {someone planting it} and, contrary to what people usually do, grafting them into a cultivated olive tree. So God will much more readily receive back the Jews because they belonged to him before [MET]! That will be like the original branches that had been cut off being grafted {like grafting the original branches that someone cut off,} back into the olive tree to which they originally belonged!
