2 Samuel 16:5 records Shimei's first appearance cursing David — the very event Abishai now cites as grounds for execution.

2 Samuel 16:7 gives Shimei's actual curse — 'man of blood, worthless man' — which Abishai references when demanding death.

2 Samuel 16:13 describes Shimei's ongoing cursing as David fled — the context Abishai is recalling in his demand.

Exodus 22:28 forbids cursing a ruler — the very law Abishai invokes to justify executing Shimei for cursing David.

In 1 Samuel 24:6, David refuses to harm Saul because he is the LORD's anointed — the same principle Abishai now uses to condemn Shimei.

In 1 Samuel 26:9, David tells Abishai not to destroy Saul, the LORD's anointed — ironic that Abishai now wants to kill Shimei for cursing that same anointed.

In 1 Kings 21:10, Naboth is falsely accused of cursing God and king, leading to his death — parallel to Abishai's demand that Shimei die for cursing David.
