There was a time Samson prayed to God against letting him die with the uncircumcised Philistine: and God saved him from dying from thirst where he killed a thousand Philistines with jawbone of an Ass [Judges 15:18-19]. Later the same Samson prayed to God to let him die with the uncircumcised Philistine: and God let him die with about three thousand Philistines he killed [Judges 16:30]

So Samson, who was praying against dying with the Philistines before, later changed and reversed his own prayer point and prayed to die with the Philistines. And the result was that he killed more (achieved more) from dying with the Philistines than he ever achieved from escaping dying with or from the Philistines. Think about this:

[John 12:24-28 GNB] - I am telling you the truth: a grain of wheat remains no more than a single grain unless it is dropped into the ground and dies. If it does die, then it produces many grains. Those who love their own life will lose it; those who hate their own life in this world will keep it for life eternal. Whoever wants to serve me must follow me, so that my servant will be with me where I am. And my Father will honor anyone who serves me. "Now my heart is troubled—and what shall I say? Shall I say, 'Father, do not let this hour come upon me'? But that is why I came—so that I might go through this hour of suffering. Father, bring glory to your name!" Then a voice spoke from heaven, "I have brought glory to it, and I will do so again."
