Romans 11:11 explains that Israel's trespass led to Gentile salvation to make Israel jealous — the theological basis for Paul's personal aim in verse 14.

Romans 9:3 reveals Paul's willingness to be cursed for his fellow Jews — the same deep love and desire for their salvation as in verse 14.

1 Corinthians 9:20-22 describes Paul becoming all things to all people to save some — directly parallel to his strategy here of provoking jealousy to save.

2 Timothy 2:10 shows Paul enduring all for the elect's salvation — the same sacrificial goal of saving others as in verse 14.

In 1 Corinthians 9:19, Paul describes becoming a slave to all to win many — the same adaptive strategy he uses here to save some Jews by provoking envy.

In 1 Corinthians 9:22, Paul says 'I have become all things to all people so that by all possible means I might save some' — a direct parallel to his aim here to save some of Israel.

1 Timothy 4:16 promises salvation for persistent teaching — similar goal of saving others, but method differs from provoking jealousy.

James 5:20 says bringing back a sinner saves his soul — parallel theme of rescuing others, though context differs.
