Jeremiah 40:15
Then Johanan the son of Kareah spake to Gedaliah in Mizpah secretly, saying, Let me go, I pray thee, and I will slay Ishmael the son of Nethaniah, and no man shall know it: wherefore should he slay thee, that all the Jews which are gathered unto thee should be scattered, and the remnant in Judah perish?

John 11:50
Parallel
In John 11:50, Caiaphas says it's expedient for one man to die for the nation — the same 'better one die than many perish' principle Johanan uses.

Parallel
In 2 Kings 25:25, Ishmael actually kills Gedaliah — the very event Johanan's proposal here sought to prevent. A tragic fulfillment.
