Anyone know where these dumb Christian phrases come from?

I keep hearing the Christians I know use some of the same phrases, which confuse me because they’re meaningless and/or redundant.

“Death, hell, and the grave.” I usually hear this one in statements like “we all deserve death, hell, and the grave” (ugh). The order is always the same, which means people heard this phrase somewhere and they’re repeating it. Where did it come from? And why say both “death” and “the grave” when they mean the exact same thing?

“For His good and for His glory.” I’ve heard several people say this one too. I understand “for His glory,” but what is “for His good”? What is God’s good? How is it different from anyone else’s good? Where did this weird phrase come from?

If any of y’all have heard these phrases or know where they originated, please let me know. I feel like I’m going crazy here lol.
