One death for the righteous and two for disbelievers?

[miracle114]

Salaam all,

Can someone please explain both Ayat and who Allah is talking about here and why some will have one death and why some will have two deaths?

Q-44:56
They do not taste death beyound the first death and GOD spare them the retribution of hell.

040:011
"They say: Our Lord! Twice have You made us die, and twice have You made us live. Now we confess our sins. Is there any way to go out?"

Thanks and God bless

Salaam also found another Ayat which talks about one death


Except for our first death, and we will not be punished?"
